1080 clothespins makes 90 chairs and we need to find out how many clothespins it takes to make 1 chair.
We can set up a proportion of the number of chairs to the number of clothespins because of the proportional relationship.
x is the number of clothes pins for 1 chair

Cross multiply to get
90*x= 1080*1
Divide both sides by 90 to isolate x
x = 12 clothespins
It takes 12 clothespins to make 1 chair.

Answer: She makes $58.50 in profit.
Step-by-step explanation:
It costs $2.50 to make each bottle
She sells each bottle for $7
2.50 * 13 = 32.5
It costs her $32.50 to make all the bottles.
7 * 13 = 91
She sells them all for $91.
91 - 32.5 = 58.5
$58.50 is the profit.
