Equation: y = 20m + 300
The cost of buying a Nintendo switch and 3 games = $360
Explanations:Let the cost of the Nintendo switch be represented by b
b = $300
Let the cost of each video game be x
x = $20
Let m represent the number of video games bought
The equation for the total cost in form of y = mx + b will be:
y = 20m + 300
Cost of buying a Nintendo switch and 3 games:
m = 3
Substitute m = 3 into the equation y = 20m + 300
y = 20(3) + 300
y = 60 + 300
y = $360
The cost of buying a Nintendo switch and 3 games = $360
