Answer:
60.
Step-by-step explanation:
As 80% of the 7th graders like hot chocolate which is equivalent to 60 people.
Combine like terms. The 5x is grouped to the 8x and the -7 isgrouped with the -55.
This means 5x + 8x = 13x and -7 - 55 = -62
The new expression is 13x - 62. We can't find the exact value of x because the expression wasn't set equal to anything.
