7.13E Simple Interest

I = Prt [Interest = principal x rate x time]

I= interest

P=principal ($)

r= interest rate (%) Change % to decimal by moving the decimal 2 places to the left

(Example 6% = 6/100 = .06 or 7.5% = 7.5/100= .075)

t= time (years)

To find the total: Add the principal + interest

7.13F Monetary Incentives

Discount: Find the percentage of the discount first. Write the percent discount as a decimal. Multiply the discount by the original price. Then subtract the discount from the original price.

A person can save the most money by using incentives to receive the greatest discount.

7.13F Monetary Incentives

Divide the original price by the denominator of the fraction. Find the discount. Then subtract the discount from the original price.

by one get one 50% off

by three, get 1 free

1/3 off the price

sale 20%e off entire purchase

A person can save the most money by using incentives to receive the greatest discount.

7.13F Monetary Incentives

The final price that the consumer pays is the original price minus the rebate.

Find the price of the coupon. Subtract the amount of the coupon from the price

coupon for $1.00 off

A person can save the most money by using incentives to receive the greatest discount.

Multiple Choice

Lashawn wants to buy some new Air Jordan 12 Retros’. He found three different stores running deals on the same shows that were originally listed at $215.

· Store Z is offering 1/5 discount off the price of the shoes.

Which statement about the price of the shoes is true?

Store Z charges $190 for the shoes.

Store Z offers the lowest price at $172.

Store Y offers a price of $180.

Store X has a price of $200.

7.10B Number Lines

When graphing an equation it will be just one closed circle on the number line.

When graphing an inequality be sure to FLIP the inequality sign if you divide by a negative number.

Multiple Choice

Which number line represents the solution to the inequality $-2x+6\ge-4$ ?

Multiple Choice

Describe how you would graph the solution to $6-5x>-4$

Closed circle at 2 and shade to the right.

Open circle at 2 and shade to the right.

Closed circle at 2 and shade to the left.

7.11A Model and Solve Equations and Inequalities

Write the equation from the model. We need two steps to solve Ax +B=C.
Circle the variable.
Undo the operations by first adding/subtracting on both sides of the equation
Next, to undo the multiplication, divide on both sides of the equation
Equations: 1x = ? or x = ? Inequalities: 1x < ?, 1x > ?, 1x ≤ ?, 1x ≥ ?

7.11A Equations and Geometry

Write the equation from the picture or problem.
All angles in a triangle are equal to 180°
Isosceles triangles have two congruent sides, two congruent angles
Supplementary (straight) -- add up to 180°
Complementary (corner) -- add up to 90°
Right angle -- 90°
Combine like terms if needed (Either variables 5x + 2x = 7x or constants 5 + 25 + 45 = 75)
Circle the variable.
Undo the operations by first adding/subtracting on both sides of the equation
Next, to undo the multiplication, divide on both sides of the equation
Equations: 1x = ? or x = ?

Multiple Choice
