Question

Billy is selling candy bars to raise money for charity. He earns $10 selling 5 candy bars. He earns $12 selling 6candy bars.Create an equation that represents the total amount of money, y, in dollars, that Billy earns selling x candy bars

Answer 1

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
