Question

Josh is selling crafts at an outdoor market. He charges $2.25 for each door hanger he has made and $3.75 for each necklace. He knows he has sold at least 20 items at the market, but he has no more than $60 in sales.

Answer 1

He sold 10 hangers and 10 neclesses

Explanation:

Given data

Let the number of door hanger be x

and the number of neckless be y

so

x+y= 20---------1

also,

2.25x+3.75y= 60---------2

Solve 1 and 2 together

From 1

x= 20-y

put this in place of x in 2

2.25(20-y)+3.75y= 60

45-2.25y+3.75y= 60

1.5y= 60-45

1.5y= 15

y= 15/1.5

y= 10

Put y= 10 in 1

x+10= 20

x= 20-10

x= 10
