Answer:
There needs to be 174 Students in the 8th grade class.
Step-by-step explanation:
173(1/3) is 58
58+17=75
A1 = 35x+25
Good guys = 40x
35x+25 = 40x
subtract 3x x from each side
25 = 5x
divide each side by 5
x = 25/5 = 5
so 5 hours they would be the same cost, anything over 5 hours and A1 would be better
so X>5 for A1 to be the better price
It is A I hope that helps for you
C ) sum
hope it helped...
sum is summation
Just one
11x+25=7x+15
11x - 7x = 15 -25
4x = -10
x = -10/4
x = -5/2
