Answer:
2.12, rounded up to 3
Step-by-step explanation:
To solve the equation, we first need to set up an equation.
Let x represent the number of scarves. We want one side of the equation to be the amount earned and the other to be the cost
45x is how much they earn since each scarf is $45
70+12x is how much they cost for rent and production
45x=70+12x
Subtract 12x from both sides
33x=70
Divide both sides by 33
x=2.12
It says we should round up so 3 scarves to break even
