How do I write two linear equations for this problem?

Answer:
$204
Step-by-step explanation:
sorry i don't know the equation just the answer
hope this helps
she needs to make 60 muffins to cover the oven cost (120/2)
then multiply 60 by 1.40 (84)
add 84 to oven cost
$204
102 muffins
Step-by-step explanation:
You can combine the sell price and the price to make. You now make 0.60 per muffin. You also need to consider the $120/day in electricity, so your equation should be:
[tex]y = 0.6x - 120[/tex]
If you need to solve how many muffins you need, just set the equation equal to 0.
0.6x-120=0
First, add 120 to the right.
0.6x=120
0.6=3/5, multiply by reciprocal to get x by itself
x=200 muffins.
