To figure this question out, we first need to figure out how much one pound of potatoes costs. To do this, we need to divide 18 by 8, and in this, we get $2.25. Then, we have to multiply this by 15 to find out how much 15 pounds of potatoes costs. This gives us $33.75, which is our answer to this question.
BIDMAS so do the 7+3 first = 10
[10 x 5 - 4] (divided by) (2+3)
then work out both brackets by doing the multiplication first
[10 x 5 - 4] = [50 - 4] = 46
(2 + 3) = 5
46 divided by 5 = 9.2
I believe it’s A
Sorry if I get it wrong :/
