Hank spend 76% of his monthly salary and saves $270 find his monthly salary
Dimas [21]

Answer:

f $270= the remaining 24% then you want to do 270/24=11.25 Then you want to multiply that by 76 and you will get $855

So $270+$855=24%+76% So his monthly salary was $1,125

If you are still confused do it in reverse! 1,125/100=11.25

11.25•24=270 & 11.25•76=855

270+855=1,125

If f(x)=x^2-7 and h(x)=7x-5, then f(h(2))=
zaharov [31]
We are given 3 equations. Using these equations we can find f(h(2)).

h(x)=7x-5
h(2)=7(2)-5
h(2)=14-5
h(2)=9

f(x)=x^2-7
f(h(2))=(7x-5)^2-7
we know the answer for h(2) by now, so we can substitute for that.
f(9)=9^2-7
f(9)=81-7
f(9)=74

so f(h(2))=74
