Final answer:
To prepare the sales budget for Alderman & Sons, we calculate the projected sales revenue for radon tests and lead tests in 2021. The projected sales revenue for radon tests is $3,468,800, and for lead tests is $3,321,200, resulting in a combined total of $6,790,000.
Step-by-step explanation:
To prepare the sales budget for Alderman & Sons, we need to calculate the projected sales of radon tests and lead tests for 2021. In 2020, the company performed 10,800 radon tests at $300 each, resulting in a total sales revenue of $3,240,000. They also performed 15,200 lead tests at $230 each, resulting in a total sales revenue of $3,496,000.
For radon tests, we expect a 7% increase in volume next year. So, the projected sales revenue for radon tests in 2021 would be $3,240,000 + 7% * $3,240,000 = $3,468,800.
For lead tests, if the price is reduced to $210 per test and there is a 5% decline in sales, the projected sales revenue for lead tests in 2021 would be $3,496,000 - 5% * $3,496,000 = $3,321,200.
Therefore, the total projected sales revenue for Alderman & Sons in 2021 would be $3,468,800 for radon tests and $3,321,200 for lead tests, resulting in a combined total of $6,790,000.
