5.2
Step-by-step explanation:
To solve for x, we want to isolate x. To do this, we need to multiply both sides by 4.
Multiply the numerators and the denominators separately.
4 • 17 = 68
1 • 13 = 13
Divide.
68 ÷ 13 = 5.23
Round to the nearest tenth.

The two expressions that represent the retail price of cars is: Retail price = 1.21c and Retail price = c + 0.21c
<em><u>Solution:</u></em>
Given that,
Rick buys remote control cars to resell
He applies a markup of 21%
Let "c" be the original price of remote control cars
To find: Expression for retail price of car
We know that,
Retail price = original price + markup
Here, markup price = 21 % of original price
Markup price = 21 % of c
Therefore, substituting the given values we get,
Retail price = c + 21 % of c
This can also be expressed as,
Thus two expressions that represent the retail price of cars is: Retail price = 1.21c and Retail price = c + 0.21c
