Question

Olivia needs $36 to buy a coat. She has saved $8 and plans to work as a babysitter to earn $7 per hour. Which inequality shows the minimum number of hours, n, that Olivia should work as a babysitter to earn enough to buy the coat? (5 points)

Select one:
a. 8 + 7n ≤ 36, so n ≤ 4
b. 8 + 7n ≥ 36, so n ≥ 4
c. 7n ≥ 36 + 8, so n ≥ 6.3
d. 7n ≤ 36 + 8, so n ≤ 6.3

Answer 1

"7 dollars per hour" can be written as 7*n

she already has 8

so 8 + 7n gives her total income

total income must be greater than or equal to 36

which inequality best describes this situation?

Answer 2

b
