Problema Solution
Last summer Bret earned $32 a day and Sandra earned $36 a day. Together they earned a total of $3560. How much did each earn, if Bret worked 5 days more than Sandra?
Answer provided by our tutors
let 'x' represent the number of days Sandra worked, then 'x+5' represents the number of days Bret worked:
3560 = 36x + 32(x+5)
solving for 'x' we have x=50
50+5 = 55
in 50 days, Sandra earned:
50*36 = 1800
in 55 days, Bret earned:
55*32 = 1760
