+65 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 ?
+36916 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 ?

+36916 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
