Question

Can someone help somehow?

Martin has a gift card to a coffee shop. Each day he buys the same coffee. This table shows the amount remaining in dollars on the gift card on different days.

Time (days) 2 4 5 7
Amount remaining ($) $24.10 $18.20 $15.25 $9.35

Identify the original value of Martin's gift card on the coordinate plane.

Answer 1

your answer is $30.00 and ill tell you why. when you subtract the the amount remaining one-by-one theres a pattern of $5.9 then 2.95 so if you add 2.95 to $24.10 you get $30
