Total money = $14,000
Sales price = $9.99
Now,
Divide the total money by sales price and it should give you the total sales required to break the business even.
So,
total sales required = 14,000 / 9.99
= 1401.401401
= 1401
Now, lets check the answer,
total sales * sales price should equal or be greater than business amount.
So,
1401 * $9.99 = $13995.99 ==> which is less than the business price.
Now, Lets add 1 to the total sales and lets check the answer again.
(1401 + 1) * $9.99
= 1402 * $9.99
= $14005.98
Since, it is greater than the business price, the total sales is 1402.
So, 1402 games must be sold to make the business even.
NOTE: THEORETICALLY, 1401 IS THE ANSWER BECAUSE IT IS ROUNDED TO THE NEAREST WHOLE NUMBER. BUT, PRACTICALLY 1402 IS THE ANSWER BECAUSE A BUSINESS IS EVEN IF AND ONLY IF THE TOTAL SALES IS EQUAL TO OR GREATER THAN THE BUSINESS PRICE.
SO, ASK YOUR TEACHER FOR WHICH IS CORRECT BETWEEN THOSE TWO.
