Answer:
Tom drove the truck for a distance of 89 miles.
Step-by-step explanation:
Base fee of truck = $18.99
Additional charge per mile = $0.75 per mile
Amount paid by Tom for the rented truck = $160.74
Let us assume Tom drove the truck for a distance of [tex]m[/tex] miles.
So, for [tex]m[/tex] miles they would charge in dollars as:
⇒ [tex]\textrm{ Base fee+ (Additional charge times miles driven) }[/tex]
⇒ [tex]18.99+(0.75\times m)[/tex]
⇒ [tex]18.99+0.75\ m[/tex]
We know the actual amount charge, so we can equate.
[tex]18.99+0.75\ m=160.74[/tex]
Subtracting both sides by 18.99 to cancel 18.99 on left side.
[tex]18.99+0.75\ m-18.99=160.74-18.99[/tex]
[tex]0.75\ m=160.74-18.99[/tex]
[tex]0.75\ m=141.75[/tex]
dividing both sides by 0.75 to isolate [tex]m[/tex]
[tex]\frac{0.75\ m}{0.75}=\frac{141.75}{0.75}[/tex]
[tex]m=89[/tex]
∴ Tom drove the truck for a distance of 89 miles.
