Hi!

Here's the help you need.
75 x 12 = 900
900 / 30 = 30

The answer is 30 which is C. Not B.

for the ppl that didn't have 30 as a choice ^^

Holiday break is coming up, don't be mean.

30 isn't a choice

C,

Find the unit rate: 75/30=2.5
Multiply your known number by the unit rate: 12x2.5=30

if you have 13 on your choice pick it

if you have 30 pick it
if you have 40 pick it
