Roshel's salary is 20% less than Jade's salary and 35% less than Anna's salary. If Jade's salary is $900 less than that of Anna's salary,
- Find Jade's salary.
- Given that Jade received a 5% salary cut, find her new salary.
(a)
100% - 20% = 80%
80% =
80100 =
45 100% - 35% = 65%
65% =
65100 =
1320

80 u |
Roshel's salary is the repeated identity. Make Roshel's salary the same. LCM of 4 and 13 is 52.
Amount that Jade's salary is less than Anna's salary
= 80 u - 65 u
= 15 u
15 u = 900
1 u = 900 ÷ 15 = 60
Jade's salary
= 65 u
= 65 x 60
= $3900
(b)
Percentage of Jade's salary after 5% salary cut
= 100% - 5%
= 95%
Jade's new salary
= 95% x 3900
=
95100 x 3900
= $3705
Answer(s): (a) $3900; (b) $3705
