Perry spent $22.50 on material to make necklaces. he used all of the material and made 15 necklaces. how much should perry charge for each necklace if he wants to make a profit of $60?

$5.5 per necklace

Step-by-step explanation:

The following equation must be satisfied:

necklaces sold * unit price = money spent on material + profit

He wants to make a profit of $60, he spent $22.50 on the material to make the necklaces and he made 15 necklaces, then:

15 * unit price = 60 + 22.5

unit price = 82.5/15 = $5.5 per necklace

he earned 78.75 in interest.

step-by-step explanation:

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
