A) Company A 4h+70
    Company B  5h+60
H= blank amount of hours 
B) Company A 4(6)+70=94
    Company B  5(6)+60=90
Company B would charge less 
C) Company A 4(7)+70=98
    Company B  5(7)+60=95
Company B will charge 3 dollars less thanCompany A
company a: 70 plus 4 times (how many hours) 
company b: 60$ plus 5 times (how many hours)
PART A 70+four(x)  B 60+5x  
THE VARIABLE REPRESENTS THE HOURS THE TRUCK WAS RENTED
PART B company a charges 9four dollars to rent the truck
              company b charges 90 dollars to rent the truck
PART C: you would have to solve the equation like this to find PART C
A: 70+four(7)=98 B: 60+5(7)=95
so the answer for part c would be he saved 3 dollars
