If the ratio from boys to girls is 3: 5 and there is a class of 32, how many boys and girls are there?

ratio is 3:5; 3 + 5 = 8

32/8 =4

so boys: 3*4 =12

girls: 5*4 = 20

boys to girls is 3:5 = 12:20

0.09x +10 is the first choice

0.07x +16 is the second choice (set the two data plans equal to each other)

0.09x +10 = 0.07x +16  (subtract 0.07x from both sides)

0.02x +10 = 16 (subtract 10 from both sides)

0.02x = 6  (divide both sides b 0.02 to isolate x)

x= 300 MB of data (the answer)
