Tiffany's salary is the repeated identity. Make Tiffany's salary the same. LCM of 7 and 13 is 91.
Amount that Tammy's salary is less than Jaslyn's salary
= 140 u - 130 u
= 10 u
10 u = 700
1 u = 700 ÷ 10 = 70
Tammy's salary
= 130 u
= 130 x 70
= $9100
(b)
Percentage of Tammy's salary after 40% salary cut
= 100% - 40%
= 60%
Tammy's new salary
= 60% x 9100
=
60100 x 9100
= $5460
Answer(s): (a) $9100; (b) $5460
