Question

, and marks it up 28
%.

Which equation can be used to find the selling price of the office chair?

X=0.28
X=1.28
X=1.028
X=0.028

Answer 1

To find the selling price of the office chair after marking it up by 28%, we need to use the original cost and include the markup.

Let the cost of the chair be $C=63$ dollars. The markup as a percentage of the cost is 28%. The selling price $S$ can be calculated using the following equation:

$$S=C+(0.28\times C)$$

This can also be expressed as:

$$S=C\times (1+0.28)=C\times 1.28$$

Thus, the correct equation to find the selling price of the office chair is:

$$S=63\times 1.28$$

From the options given, the relevant multiplier for the markup which you would use in the calculation is:

X = 1.28
