y = 11x
Step-by-step explanation:
The amount earned selling 5 candy bars = $10
for 1 candy bar = $10/5
1 candy bar costs = $2
The amount earned selling 6 candy bars $12
The cost of 1 candy bar = $12/6
The cost of 1 candy bar = $2
From the above: in both scenarios, the cost of each candy bar was $2
If total amount of money earned = y
And number of candy sold = x
Then the equation:
total amount of money earned = number of candy sold × cost of each candy
number of candy sold = 5 + 6 = 11
y = 11 × x
y = 11x
Hence, an equation that represents the total amount of money, y, in dollars, that Billy earns selling x candy bars is y = 11x
