Equation: 1.15 c = 40
Solution: $34.78
Step-by-step explanation:
The given is:
- Sam bought a computer game that costs 15% more than a printer cartridge
- c is the cost in dollars, of the printer cartridge
We need to write an equation that can be used to find c, and then
find the value of c
∵ The cost of the printer cartage = $c
∵ The computer game costs 15% more than a printer cartridge
- That means add the cost of the cartage by 15% of it to find the
cost of the computer game
∴ The cost of the computer game = c + 15% × c
∵ 15% = 15 ÷ 100 = 0.15
∴ The cost of the computer game = c + 0.15 c
- The two terms of c (1 + 0.15)
∴ The cost of the computer game = $1.15 c
∵ The cost of the computer game = $40
- Equate the two expressions of the cost of the game
∴ 1.15 c = 40
The equation that can be used to find c is 1.15 c = 40
Solve the equation to find c
∵ 1.15 c = 40
- Divide both sides by 1.15
∴ c = $34.78
The cost of the printer cartridge is $34.78
Equation: 1.15 c = 40
Solution: $34.78
