Question

A contractor employed 5 adults and 3 teenagers for one day and paid them

Answer 1

Hello
5 adults and 3 teenagers for one day paid them a total of $224 per hour
5A + 3T = 8 * 224
3 adults and 5 teenagers for one day paid them a total of $160 per hour
3A + 5T = 8 * 160
Adding both
=> 8A + 8T = 8 * 224 + 8 * 160
=> A + T = 384
2A - 2T = 8(64)
=> A - T = 256
2A = 640
=> A = 320
T = 64
The hourly rate paid day to each adult is $320
