In $20202020,$ ColeCole $$& Sons, a small$$ environmental$-$testing firm, performed $12$ comma $20012,200$ radon tests for $ $280$$$280$ each and $16$ comma $60016,600$ lead tests for $ $190$$$190$ each. Because newer homes are being built with$$ lead$-$free pipes,$$ lead$-$testing volume is expected to decrease by $1313\%$ next year.$$ However, awareness of$$ radon$-$related health hazards is expected to result in a $66\%$ increase in$$ radon$-$test volume each year in the near future. Jim ColeCole feels that if he lowers his price for lead testing to $ $170$$$170$ per$$ test, he will have to face only a $77\%$ decline in$$ lead$-$test sales in $20212021.$
