Robert and his coworkers brought 11 work trucks to a service station for oil changes. While there they also put 6 gallons of gas
Free_Kalibri [48]

Answer:

The cost of an oil change for 1 truck was $42

Step-by-step explanation:

Let

x -----> the cost of an oil change for 1 truck

y -----> the cost of gas for 1 truck

z ----> the total bill

we know that

z=11[x+y]

we have

z=\$694.32

y=(6)(3.52)=\$21.12

substitute and solve for x

694.32=11[x+21.12]

x=(694.32/11)-21.12

x=\$42
