rodney needs $90 to buy a fish tank. he has saved $35 and plans to work as a babysitter to earn $5 per hour. which inequality sh
kykrilka [37]
N = number of hours.

$5 per hour, total = 5*n = $5n

Since $35 has been saved. 

The amount saved plus the amount got from baby sitting should be greater or equal to the $90 cost.

5n + 35 ≥ 90

5n ≥ 90 -35

5n ≥ 55

n ≥ 55/5

n ≥ 11

So Rodney should baby sit for at least 11 hours, that is 11 and above.
