So allison spent 3/5 meaning she saved 2/5 because 3/5 + 2/5 = 5/5
change the 2/5 into decimals by 2 ÷ 5 = 0.4
multiply $55 with 0.4
55 x 0.4 = 22
so she ends up saving $22
A. 44.99 + 0.75(29.99)x = 44.99 + 22.49x
B. 1.08(44.99 + 22.49x )
C. 1.08(44.99 + 22.49(4)) = 1.08 (44.99 + 89.96) = 1.08(134.95) = 145.75
It is one answer with multiplicity 2



Be carefully, normally there is no a in your expression. I think you made a mistake.
Hope this helps !
