Amount that Zane earned from Shop F on Thursday in percentage = 100%
Amount that Zane earned from Shop E on Thursday in percentage
= 100% + 25%
= 125%
125% =
125100 =
54 Fraction of the total earnings that Zane earned from Shop F
= 1 -
25 =
35(3) = (4)
15 u - 378 = 8 u + 378
15 u - 8 u = 378 + 378
7 u = 756
1 u = 756 ÷ 7 = 108
Amount that Zane earned from Shop E over the two days
= 5 u - 126
= 5 x 108 - 126
= 540 - 126
= $414
Answer(s): $414
