In 2017​, Lippart ​& Sons, a small​ environmental-testing firm, performed 11,000 radon tests for $330 each and 15,000 lead tests for $240 each. Because newer homes are being built with​ lead-free pipes,​ lead-testing volume is expected to decrease by 15​% next year.​ However, awareness of​ radon-related health hazards is expected to result in a 7​% increase in​ radon-test volume each year in the near future. Jim Lippart feels that if he lowers his price for lead testing to $220 per​ test, he will have to face only a 4​% decline in​ lead-test sales in 2018.Required:a. Prepare a 2018 sales budget for Hart & Sons assuming that Hart holds prices at 2017 levels. b. Prepare a 2018 sales budget for Hart & Sons assuming that Hart lowers the price of a lead test to $200.
