A taxi charges a flat fee of $4.00 plus $3.25 per mile. How much will it cost to travel 8.3 miles? Round your answer to the nearest cent.

$30.98

Step-by-step explanation:

Make an expression

It costs 3.25 per mile(x), and there is a cost of 4 no matter how many miles are traveled.

3.25x+4

To find how much 8.3 miles will cost, substitute 8.3 in for x

3.25x+4

3.25(8.3)+4

Multiply

26.975+4

Add

30.975

Round to the nearest cent/hundreth

30.98

So, it costs $30.98 to travel 8.3 miles

Hope this helps! :)
