The percent of commission is 7.3% to the nearest tenth of a percent
Step-by-step explanation:
The given is:
- Bill earns a commission on every sale he makes
- He sells a bed for $591 and earns a $43 commission
We need to find the percent commission
To find the percent of commission divide the commission by the selling price and multiply the answer by 100%
∵ His commission is $43
∵ The selling price is $591
∵ The percent of commission = × 100%
∴ The percent of commission = × 100%
∴ The percent of commission = 7.2758%
- Rounded it to the nearest tenth percent
∴ The percent of commission = 7.3%
The percent of commission is 7.3% to the nearest tenth of a percent

The equation of a quadratic function in vertex form is given by:
Where (h,k) is the vertex.
It was given in the question that the vertex of the parabola is (-1,4).
When we substitute the vertex into the formula we get:
The parabola also passes through (4,19) hence it must satisfy its equation.
We divide both sides by 25 to get:
Hence the quadratic function is:
