Kimberly's income is 30% less than Jade's income and 35% less than Cindy's income. If Jade's income is $700 less than that of Cindy's income,
- Find Jade's income.
- Given that Jade received a 35% income cut, find her new income.
(a)
100% - 30% = 70%
70% =
70100 =
710 100% - 35% = 65%
65% =
65100 =
1320

Kimberly's income is the repeated identity. Make Kimberly's salary the same. LCM of 7 and 13 is 91.
Amount that Jade's income is less than Cindy's salary
= 140 u - 130 u
= 10 u
10 u = 700
1 u = 700 ÷ 10 = 70
Jade's income
= 130 u
= 130 x 70
= $9100
(b)
Percentage of Jade's income after 35% income cut
= 100% - 35%
= 65%
Jade's new income
= 65% x 9100
=
65100 x 9100
= $5915
Answer(s): (a) $9100; (b) $5915
