Question 9 (5 points)
(03.04 LC)
The sum of two numbers is 52. The greater number is 4 more than the smaller number. Which equation can be used to solve for the smaller number? (5 points)
a
x − (x + 4) = 52
b
x + (x + 4) = 52
c
x(x + 4) = 52
d
x(x − 4) = 52

Gavin needs $80 to buy a fish tank. He has saved $8 and plans to work as a babysitter to earn $9 per hour. Which inequality shows the minimum number of hours, n, that Gavin should work as a babysitter to earn enough to buy the fish tank? (5 points)
a
8 + 9n ≥ 80, so n ≥ 8
b
8 + 9n ≤ 80, so n ≤ 8
c
9n ≥ 80 + 8, so n ≥ 9.8
d
9n ≤ 80 + 8, so n ≤ 9.8

Natalie works in a toy shop and earns $43 per day. She earns an extra $3 for each toy she sells. If Natalie wants to earn at least $70 per day, which inequality shows the minimum number of toys, n, that she should sell? (5 points)
a
43 + 3n ≥ 70, so n ≥ 9
b
43 + 3n ≤ 70, so n ≤ 9
c
43 + 3n ≥ 70, so n ≥ 24
d
43 + 3n ≤ 70, so n ≤ 24

Chad wants to buy some books over the Internet. Each book costs $10.01 and has a shipping cost of $9.96 per order. If Chad wants to spend no more than $50 for his books, which inequality shows the maximum number of books, p, that he can buy? (5 points)
a
9.96p − 10.01p ≤ 50, so p ≤ 1
b
9.96p + 10.01p ≤ 50, so p ≤ 2
c
9.96 − 10.01p ≤ 50, so p ≤ 3
d
9.96 + 10.01p ≤ 50, so p ≤ 4
