Question

A taxi charges a flat rate of $2.25 plus an additional $0.50 per mile.

Annie has at most $10 to spend on the cab ride. Could Annie travel
18 miles?

Answer 1

No, she can't

Explanation:

The equation to solve the problem is the following:

y=0.5x+2.25

where x is the # of miles and y is the amount charged based on the flat rate and the additional $0.50 per mile (x).

y should be less than or equal to 10 since that's the maximum Annie can pay.

y
`\leq`10

Substitute x with the number of miles asked (18)

y = 0.5(18) + 2.25 = 11.25

Annie would have to spend $11.25 to travel 18 miles, but she can spend at most $10 ⇒ she can't travel 18 miles.

Answer 2

No, Annie could not travel 18 miles.
