Question

Peter's weekly wages are #20.00 for the first 20 weeks and #40.00 for next 24 weeks. Find his average weekly wage for the remaining 8 weeks of the years if his average weekly wage for the whole year is #30.00

Answer 1

20*20 + 40*24 + 8x = 30(20+24+8)

Answer 2

let x be the average wage for the remaining 8 weeks

20(20) +8x + 24(40) = 52(30)

solve for x

Answer 3

let x be the average wage for the remaining 8 weeks
24+20+8=52weeks
#20*20+#24*40+#x*8=#30*52
400+960+8x=1560
8x+1360=1560
8x=1560-1360
8x=200
8x/8=200/8
x=#24
