Use comparison
x/27 = 28/3
x = 28/3 × 27
x = 252
She can bake 252 cupcakes
Using the equation, the amount of ribbon she needs to sell to break even is 50 ribbons.
<h3>How to represent system of equation and solve?</h3>
x = number of ribbons
y = expenses or revenue
Therefore, the system of equation for this situation is as follows;
y(expenses) = 23 + 0.04x
y = 23 + 0.04x
He charges $0.50 per ribbon. Therefore,
y(revenue) = 0.50x
y = 0.50x
Therefore, for her to break even,
23 + 0.04x = 0.50x
23 = 0.46x
x = 23 / 0.46
x = 50
Therefore, she needs to sell 50 ribbons for her to break even.
