Budget and miles?

Question

The Chan’s family are in need of renting a truck and their budget is $85 for the rental fee. They manage to rent a truck at a daily rate of $25 for a day plus 10 cents per mile driven. Find the maximum number of miles that they can drive on a One day rental?

Answer 1

Convert cents to dollars:

10cents=$0.1

$85=$25+$0.1•y

budget=daily rate for one day + price per mile driven in $ multiplied by y miles

solve for y

$85-$25=$0.1•y

$60=$0.1•y

$60/$0.1=y

y=600 miles

Answer:

600  miles
