Question

Please help. I thought I worked it out correctly but the answer is apparently wrong

Answer 1

ready-steady paint

Explanation:

if he needs 12 tins, and purchased from paint -O mine, he would spend (12/3) X 7.50 = 4 x 7.50 = £30

from ready steady, he can buy 4 for £11. he needs 12.

so he will spend (12/4) X 11 = 3 X 11 = £33. but he can get 15% off. 15% off is the same as multiplying by 0.85.

33 X 0.85 = £28.05.

so he his better purchasing from ready steady paint
