Answer:
least number of quilts is gonna be 10
Step-by-step explanation:
ok...so profit = revenue - expenses
n = # of quilts
revenue : (the money made from the quilts)
she sold each quilt for 35 bucks......35n
expense : (the money Norma spent on the materials)
the cost of fabric is 13.55 per quilt......13.55n
so ur expression is :
revenue - expenses
35n - 13.55n <==== this is part A
==========================
she wants to make a profit of 200...
P = revenue - expenses
200 = 35n - 13.55n
200 = 21.45n
200 / 21.45 = n
9.32 = n.......gonna have to round up to 10 <==== part B
ok...so 9 quilts is not gonna be quite enough...so shes gonna have to make 10.
