Question

It cost $20 a day to rent a bike. create an equation using c (cost) and d(days)

Answer 1

$20d = c

Explanation:

Since the cost is $20 per day, $20d ($20 for how many days) would be the start of the equation.

C = cost, and $20d will determine the cost, so $20d = c

is your final answer/equation.
