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

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
