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

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

And

Pedro wants to buy some shirts over the Internet. Each shirt costs $10.01 and has a shipping cost of $9.94 per order. If Pedro wants to spend no more than $70 for his shirts, which inequality shows the maximum number of shirts, p, that he can buy?

A.9.94 + 10.01p ≤ 70, so p ≤ 6

B.9.94 − 10.01p ≤ 70, so p ≤ 7

C.9.94p + 10.01p ≤ 70, so p ≤ 8

D.9.94p − 10.01p ≤ 70 ≤ 60, so p ≤ 9

KK....this is VERY similar to your other questions...... what have you tried to solve this one ?

Same thing here, KK.... what do YOU think the answer might be? Did you read the other answers to learn how to do these Q's ?

First one:

Gavin needs at least 80 dollars sooooo >= 80

starts with 8 dollars and adds 9 dollars per n hour

8 + 9n >= 80

9n >=72

n >= 8 Answer A

Second one :

Pedro wants to spen = to or less than 70 so <= 70

9.94 shipping per order and 10.01 per p is the total cost

9.94 + 10.01 p <= 70

10.01 p <= 60.06

p <= 6
