Question

Cookies are being sold in the cafeteria to raise money for the cheerleaders. One giant cookie costs $1 while each one bought after costs $0.75. Write an equation in slope-intercept form to represent the situation.

Answer 1

y = 0.75x + 1

Explanation:

Here, we want to write an equation in slope-intercept form to represent this information

Since $1 is the cost of 1 only, this represents our y intercept

It means if we are not interested in purchasing more than 1, our cost will be $1

Now, for each one bought after, we have a rate of $0.75 per one

Mathematically, that will be $0.75 times the number bought after

Hence. we have that;

y = 0.75x + 1

if 1, x = 0; so we have cost of 1 as $1
