A sporting goods store buys a basketball for $10.00 and then adds a 110% markup to the price. How much will the basketball sell for in the store.

The basketball will sell for $21 .

Step-by-step explanation:

Hi, to answer this question, first, we have to multiply the cost of the basketball (10) by the percent markup in decimal form (divided by 100).

Mathematically speaking:

10 x (110/100) = $11

Now, we have to add the markup amount (11) to the cost (10) to obtain the selling price:

10 +11 = $21

The basketball will sell for $21 .

The price will be $21 on the store.

Step-by-step explanation:

In order to solve this question we can use a rule of three in such a way that $10 represents 100% and "x" represents 110%, we then sum "x" to the value the ball was bought which is 10 and that will be it's price in the store. We have:

$10 -> 100%

$x -> 110%

10/x = 100/110

100*x = 110*10

100*x = 1100

x = 1100/100 = 11

store price = 10 + x = 10 + 11 = 21

The price will be $21 on the store.
