Question

You have a gift card for a coffee shop worth $90. Each day you use the card to get a coffee for $4.10. what is the value of the card after you buy your 8th coffee

Answer 1

$57.20

Explanation:

So the card starts off with $90, we spend $4.10 each day

To figure this out quick, take $4.10 and multiply it by 8

$4.10 x 8 =$32.80

Now subtract:

$90 - $32.80 = $57.20
