Nicole's salary is 10% less than Barbara's salary and 40% less than Usha's salary. If Barbara's salary is $1350 less than that of Usha's salary,
- Find Barbara's salary.
- Given that Barbara received a 25% salary cut, find her new salary.
(a)
100% - 10% = 90%
90% =
90100 =
910 100% - 40% = 60%
60% =
60100 =
35

| 27 u |
30 u |
45 u |
Nicole's salary is the repeated identity. Make Nicole's salary the same. LCM of 9 and 3 is 27.
Amount that Barbara's salary is less than Usha's salary
= 45 u - 30 u
= 15 u
15 u = 1350
1 u = 1350 ÷ 15 = 90
Barbara's salary
= 30 u
= 30 x 90
= $2700
(b)
Percentage of Barbara's salary after 25% salary cut
= 100% - 25%
= 75%
Barbara's new salary
= 75% x 2700
=
75100 x 2700
= $2025
Answer(s): (a) $2700; (b) $2025
