In 2017​, Cole & Sons, a small​ environmental-testing firm, performed 11,200 radon tests for $290 each and 15,800 lead tests for $240 each. Because newer homes are being built with​ lead-free pipes,​ lead-testing volume is expected to decrease by 12​% next year.​ However, awareness of​ radon-related health hazards is expected to result in a 4​% increase in​ radon-test volume each year in the near future. Jim Cole feels that if he lowers his price for lead testing to $230 per​ test, he will have to face only an 7​% decline in​ lead-test sales in 2018. Requirements 1. Prepare a 2018 sales budget for Cole ​& Sons assuming that Cole holds prices at 2017 levels. 2. Prepare a 2018 sales budget for Cole ​& Sons assuming that Cole lowers the price of a lead test to $230.
