Kristin paid $2.50 per black-and-white photo B and $6 per color photo C to have some photos restored. What was the total amount A that she paid if she had 8 black-and-white and 12 color photos restored?
A = 2.5B + 6C
A = 2.5(8) + 6(12)
A =
A = $92.00
ANSWER

9. = n + 30 4 (n + 9) – 3(2 + n) 4 (n + 9) – 3(2 + n) = 4n + 36 – 6 – 3n
Problem A
Simplify an expression
Simplify the expression
4 (n + 9) – 3(2 + n)
SOLUTION
Apply
the
Distributive
Property
4 (n + 9) – 3(2 + n)
= 4n + 36 – 6 – 3n
Combine like terms.
= 4n + 36 – 6 – 3n
= n + 30

13. Problem A
EXERCISING
Solve a multi-step problem
Your daily workout plan involves a total of 50 minutes of running and swimming. You burn 15 calories per minute when running and 9 calories per minute when swimming. Let R be your running time in minutes. Find the number of calories you burn in your 50 minute workout if you run for 20 minutes. 13

EXERCISING
Solve a multi-step problem
Your daily workout plan involves a total of 50 minutes of running and swimming. You burn 15 calories per minute when running and 9 calories per minute when swimming. Let R be your running time in minutes. Find the number of calories you burn in your 50 minute workout if you run for 20 minutes.
SOLUTION
The workout lasts 50 minutes, and your running time is R minutes. So, your swimming time is (50 – R) minutes.
STEP 1
Write a verbal model. Then write an equation. 14

15. C = 6R + 450 C = 6(20) + 450 = 570 ( ) R 50 – 9 15R + C = 9R – 450 15R
Problem A
EXERCISING
Solve a multi-step problem ( ) R 50 – 9
15R + C =
Write equation. 9R –
450
15R + =
Distributive property
450 6R + =
Combine like terms.
STEP 2
Find the value of C when R = 20
C = 6R + 450
Write equation.
Substitute 20 for r. Then simplify.
C = 6(20) = 570
You burn 570 calories in your 50 minute workout if you run for 20 minutes.
ANSWER 15

16. Problem B
EXERCISING
C = • R • (W – R)
Suppose your workout (W) lasts 45 minutes.
How many calories do you burn if you run for 20 minutes?

17. Problem B
EXERCISING
C = • R • (W – R)
Suppose your workout (W) lasts 45 minutes.
