    Yesterday Hadi earned: $120

    Today he will earn: $120*85% = $102

    (You times the amount yesterday by 85% because you want to find the 15% less of 100% of the amount he's earned yesterday. Therefore, to find 15% less than yesterday you multiply it by 85% (100% - 15%))

    Tomorrow he will earn: $102*115% = $117.30

    (Same thing here, however you are finding 15% more than 100% today. Therefore, you multiply the amount he earned today it by 115% (100% + 15%))

    To find the amount he earns for the three days you must add the amount earned of yesterday, today and tomorrow earned from the working above.

    Therefore, Hadi expects to earn:

    Yesterday + Today + Tomorrow = 120 + 102 + 117.30 = $339.3
