The average weight is 114 pounds of all 5 children.
3 * 120 = 360
2 * 105 = 210
210 + 360 = 570
570 / 5 = 114
The scenarios which matches the equation given are scenarios 3 and 4
Scenario 1 :
Let :
Cost of hamburger = x
Number of hamburgers = 1
Cost of Burritos = y
Number of burritos = 5
Amount spent on soda = $20
Total cost = $20
x + 5y + 2 = 20
Scenario 2 :
Price per shirt = x
2 shirts = x
A pair of shirt = x
5 pairs = 5x
Total Amount spent = $20
Additional amount spent = $2
x + 5x = $20 + $2
x + 5x = 22
Scenario 3 :
Amount spent per person = x
Amount spent on Sunday (2 persons) = 2x
Amout spent on Monday = number of plays × 2x = 5(2x)
Shoe rental = $2
Total Amout spent = $20
Equation : 2x + 5(2x) + 2 = 20
Scenario 4 :
Let :
Cost per diamond = x
Cost of 2 diamonds = 2x
Cost of gem = 5 times the cost of 2 diamonds = 5(2x)
Tax paid = $2
Total amount spent = $20
Equation : 2x + 5(2x) + 2 = 20
Hence, only scenario 3 and 4 matches the equation.
