Answer 1

So the answer is £67.08p

Explanation:

156 X 0.32 + 4992 - so £49.92

Then, (200-156) X0.39 = £17.16

£17.16 + £49.92 = £67.08!! - hope this helps

Answer 2

£67.08

Explanation:

44 apples weigh more than 90 grams.

156 apples weigh 90 grams or less.

0.39 x 44 = £17.16

0.32 x 156 = £49.92

49.92 + 17.16 = £67.08
