Answer 4

I thought the 0.10 was coming from 1.55-0.65= 0.9 not 0.10 so I am still working on this one.

Answer 5

Take ure tym

Answer 6

The answer is B Idk how they got it

Answer 7

try 0.9 not 0.10 because when you subtract 1.55-.065 doesn't = 0.10

Answer 8

Answer 9

Answer 10

Answer 11

copycat lol

Answer 12

Forget about the 250 grams for the moment. If you have to pay $0.10 (10 cents) for 100 grams, and you paid $0.10 that means you paid for 100 grams
if you paid 0.20 , you paid for 200 grams
if you paid 0.90, you paid for 900 grams
notice that the number of 100 gram chunks you paid for is 0.90/0.10= 9
9 chunks of 100 grams or 900 grams

Answer 13
