35 u |
Comparing Tina
and Emily in the end |

$2480 less |
Tina's salary at first is repeated. Make Tina's salary at first the same. LCM of 2 and 5 is 10.
Amount that Tina will have less than Emily in the end
= 35 u - 4 u
= 31 u
31 u = 2480
1 u = 2480 ÷ 31 = 80
Emily's salary
= 35 u
= 35 x 80
= $2800
Answer(s): $2800
