Question

Myra owns a car service that charges a $5 flat rate and an additional $0.50 per mile, which is represented by the equation y = 0.5x + 5, where x is the number of miles and y is the total cost.

How much is the total cost for a car with 30 miles?
$10
$15
$20
$35

Answer 1

ok so you see how it says X is number of miles? and the question says there are 30 miles? well put 30 in place of x and solve it.

does this make sense or do you need a visual?

Answer 2

Since we already have the equation, the problem states "an additional $0.50 per mile" so this means that we would plug in that 30 miles into x. So this makes y=.5(30)+5

Ok

Answer 5

y = 0.5x +5
y = 0.5(30) + 5
y = 15 + 5

Just add 15 + 5 to get your answer.
