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?
8 + 7n ≤ 36, so n ≤ 4
8 + 7n ≥ 36, so n ≥ 4
7n ≥ 36 + 8, so n ≥ 6.3
7n ≤ 36 + 8, so n ≤ 6.3

Answer 1

Answer:

8 + 7n ≤ 36, so n ≤ 4

Step-by-step explanation:

Olivia needs $36 to buy a coat. She has saved $8 and plans to work as a babysitter to earn $7 per hour.

LEt n be the number of hours

Initial saving is $8 and earns $7 per hour

$7 for 1 hours , so 7n earned for n hours

Total amount is $7n+8$

Olivia needs $36 to buy a coat.So inequality becomes

$7n+8\leq 36$

Now we solve for n

Subtract 8 from both sides

$7n \leq 28$

Divide both sides by 7

$n \leq 4$

8 + 7n ≤ 36, so n ≤ 4

Answer 2

█ Solution █

✦ Since Olivia has already saved 8 dollars, the inequality would be addition.
✦ The only two choices for that would be choice #1 or #2
✦ Since she's earning 7 dollars per hour, the answer would be the first choice.
✦ 8 + 7n ≥ 36, so n ≥ 4

Answer: Choice 1
