A hobby store pays $20 wholesale for drones and marks them up 40%. What is the retail price of each drone?

$28

Step-by-step explanation:

To find the retail price you have to find 40% of 20 and then add that value to 20.

To find 40% of 20 let's convert 40% into decimal form: 0.4

Then you multiply: 20 * 0.4 = 8

Now you add 8 to the original 20: 20 + 8 = 28

The retail price of each drone is $28.

I hope this helps :)

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
