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 k
nows he has sold at least 20 items at the market, but he has no more than $60 in sales.
1 answer:
Answer:
He sold 10 hangers and 10 neclesses
Step-by-step 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

There is a total of 75 (25+50=75) in the entire collection.
And 50 of them are from the US
50/75=2/3
2/3 is the simplest form.
