Question

A meal plan lets students buy $20 meal cards. Each meal card lasts about 8 days. write and graph equation

Answer 1

Step-by-step explanation:

Given that,

A meal plan lets students buy $20 meal cards.

Each meal card lasts about 8 days.

Let us assume that y denotes number of days for a 20 dollar meal card i.e. $20 every 8 days.

Let x = number of $ for another day.

So,

$y=\dfrac{8}{20}x+8$

$y=\dfrac{2}{5}x+8$

Hence, this is the required equation.
