The correct answer would be B. Hope this helps, and please mark me the brainliest, we can be friends!!
So we know that there are 8 slices per large pizza (7), so a total of 56 slices
we would set up a proportion
5/8=x/56
8 times 7 gives you 56, and we would do that same thing to the 5 (multiply it by 7) to get 35?
so now we know that 35 out of 56 slices were eaten
56-35 is 21
so there are 21 slices left over
30X15=450. 450:100= 4,50. 30+4,50= 34,50
