Solution:
Consider the following expression:
2.5 x 8(20+5)
Solving the expression inside the parentheses first, we obtain:
2.5 x 8(25)
this is equivalent to:
2.5 x 200
this is equivalent to:
500
so that, we can conclude that the correct answer is:
500
After 20% reduction the price is $48 which means $48 is only 80% of the original price...so let x= original price
<span>48=.8x </span>
<span>60=x </span>
<span>it was $60
</span>
A. 4x+5=4x-5
4x+10=4x
10=0
B. 4x+5=4x+5
C.4x+5=1/4+5
4x=1/4
16x=1
x=16
D. 4x+5=8x+10
-4x=5
x=-5/4
