Question

Wiyot is earning money for a longboard by selling lemonade at the soccer fields. Being a precocious and poorly-supervised 12 year old, Wiyot has no transportation and decides to use water from a nearby river.

Business is booming! He sells 33 lemonades on the first day, and 6 additional lemonades each day as the summer heats up. How many TOTAL cups of giardia-laced lemonade will Wiyot have sold by the time his parents get a call from county health officials on day 8?

Answer 1

Answer: 75 cups of giardia-laced lemonade

Explanation:

On the first day he sells 33 lemonades, so we will start with "33 +" for our equation. Then, he sells 6 additional lemonades each day further as the summer heats up. If x is equal to days, the next part will be "6(x-1)" for our equation.

Lastly, we will plug in an 8 for x, number of days, and solve,

33 + 6(x - 1)

33 + 6(8 - 1)

75
