Answer:
She should have about $150
Step-by-step explanation:
If you round all the numbers you get..
140-50-20+80
140-50-20=70
70+80=150
2440 is what percent of 71,492
percent formula : is/of = %/100
is = 2440
of = 71492
% = x
now we sub
2440/71492 = x/100
cross multiply because this is a proportion
(71492)(x) = (2440)(100)
71492x = 244000
x = 244000 / 71492
x = 3.413%
I believe it would be A.. 2/y
