A supermarket is carrying out a promotion in January. Andrew is collecting vouchers from the supermarket. Each red voucher is worth 7.5 points. Each blue voucher is worth 10 points. Each yellow is worth 13 points.

Question

Andrew collects 150 vouchers in January.

3/5 of the vouchers are red.
22% of the vouchers are blue.
The rest are yellow.
To get a prize Andrew must collect 1350 points.
Will Andrew get a prize in January?

Answer 1

well, just add up the points.
3/5 * 150 * 7.5
+ 0.22 * 150 * 10
+ (1 - 3/5 - 0.22) * 150 * 13
