Answer:
Total amount spend = $6.96
Step-by-step explanation:
Given:
Amount of Skittles = 1.5 pound
Amount of Reese = 4.5 pound
Amount of chips = 2.3 pound
Candy cost = $0.70 per pound
Chips cost = $1.20 per pound
Find:
Total amount spend
Computation:
Total amount spend = [Amount of Skittles+Amount of Reese][Candy cost]+[Amount of chips][Chips cost]
Total amount spend = [1.5+4.5][0.70]+[2.3][1.20]
Total amount spend = 4.2 + 2.76
Total amount spend = $6.96
Answer:
He sold 100 rackets for $ 20
Step-by-step explanation:
To start, we have to make 2 equations, one that represents the number of rackets and the other the money
x + y = 500
x * 20 + y * 45 = 20000
we clear x in the first equation
x + y = 500
x = 500 - y
we replace x in the second equation with (500 - y)
x * 20 + y * 45 = 20000
(500 - y) * 20 + y * 45 = 20000
10000 - 20y + 45y = 20000
-20y + 45y = 20000 - 10000
25y = 10000
y = 10000/25
y = 400
we replace x in the first equation with the value obtained
x = 500 - y
x = 500 - 400
x = 100
He sold 100 rackets for $ 20
