Question

HELP ME PLEASE!!

You go to a bakery and buy 30 items to share with your A1, all muffins and
croissants. Each muffin cost $3.50, and each croissant cost $2.75. If you
spent a total of $96.00, how many croissants did you buy?

Answer 1

12

Explanation:

To solve this problem you would have to create a system of equations and solve them to find the point of intersection between the two graphs.

Let x equal the amount of muffins and y equal the amount of croissants

Because there was a total of 30 items bought, we can make this expression for our first equation:

x + y = 30

Next, we use the same logic to apply to the total cost for the items:

3.50x + 2.75y = 96.00

If you have a graphing calculator (I used desmos) you can put these two expressions in the calculator and take note of the point of intersection which is (18,12). This point means that 18 muffins and 12 croissants will make both expressions true.
