Answer 1

He will take the bus

Explanation:

$3.00 + ($.50 x 15) = $10.5

Answer 2

Take the bus

Explanation:

Cost to go home is equal to the flat fee plus the miles time the mileage rate

C = 3 + .5m

If must be less than 10 or he will take the bus

10 > 3 + 5m

If the miles are 15

10 > 3 +.5 (15)

10 > 3 +7.5

10 > 10.50

He will need to take the bus
