Question

Marc pays a flat rate of $40 per week to rent a motor boat. He pays an additional $6 for every liter of fuel used. This week, marc used 8 liters of fuel.

Answer 1

$88

Explanation:

Let us make a function for this equation:
40w+6l (w being the number of weeks and l being the amount of fuel used)

When plugging in 1 for w and 8 for l, we get 40+48, which gives us our answer of $88.
