Rate and Point Question

Question

At Eagle Bay, it costs $10 per hour to rent a canoe. Nick and his friends rented a canoe for 3 hours and paid $45.

Then find the cost to rent canoe for 8 hours.

Answer 1

What we know: rate = $10 per hour, price for 3 hours = $45

To calculate the flat fee (the additional charge to our hourly rate), we need to first calculate hourly cost for three hours:

time x cost = 3 hours x $10 per hour = $30 total

Since it tells us that 3 hours costs $45, we can then do:

$45 - $30 = $15 to know that we need to add a $15 fee to whatever we calculate for our hourly rate

Using this logic for 8 hours:

time x cost = 8 hours x $10 per hour = $80 dollars

Add the $15 fee (that we calculated in step 1):

$80 + $15 = $105

Answer: $95 total for 8 hours
