Question

write 2 equations and solve all 28 members of the crestview high ski club went on a ski trip. members can rent skis for $16 per day or snowboards for $19 per day. the club paid a total of $478 for all rentals. How many rented skis, and how many rented snowboards

Answer 1

X = ski rentals, y = snowboarding rentals

x + y = 28......x = 28 - y
16x + 19y = 478

16(28 - y) + 19y = 478
448 - 16y + 19y = 478
-16y + 19y = 478 - 448
3y = 30
y = 30/3
y = 10

x + y = 28
x + 10 = 28
x = 28 - 10
x = 18

so 18 rented skis and 10 rented snowboards
