Question

The cost in dollars, y, to participate x days in a bike tour is a linear function. Lin's bike tour is described by the equation y = 5x + 50. The cost of Max's bike tour is $120 for a 14-day bike tour. If both Lin and Max take 14-day tours, whose bike tour costs less? Lin Max They cost the same amount

Answer 1

They cost the same amount

Explanation:

Given

Lin:
`y = 5x +50` where x = 14

Max:
`\$120` for 14 days

Required

Which is less expensive?

Max charges has been given from the question as; $120 for 14 days.

To determine Lin's, we simply substitute 14 for x in
`y = 5x +50`

`y = 5 * 14 + 50`

`y = 70 + 50`

`y =120`

The above result of y shows that Max charges for 14 days is also $120.

Hence, they (Lin and Max) cost the same because they both equal to $120 for 14 days
