Sebastian is ordering a taxi from an online taxi service. The taxi charges $3 just for the pickup and then an additional $0.75 per mile driven. How much would a taxi ride
cost if Sebastian is riding for 10 miles? How much would a taxi ride cost that is m
miles long?

$10.50 for 10 miles & 0.75m+3 for "m" miles

Step-by-step explanation:

if the taxi charges $3 just for showing up, then in the formula (y=mx+b) 3 would be your "b"

y = mx + 3

if the taxi is charging $0.75 per mile, the mile will be your "x" in the formula, and 0.75 will represent your "m" in the formula

y = 0.75x + 3                 - this is your equation for "m" miles

to find how much for 10 miles, substitute 10 for "x" in your formula

y = 0.75 (10) +3

y = 10.50

so it is $10.50 for 10 miles, including the 3 dollar pick up fee.
