P(2000)=2.25(2000)-7000=-\$2500 b.) P(5000)=2.25(5000)-7000=\$4250 c.) At breakeven, revenues equal cost. Since profit equals revenues minus cost, then profit equals zero. She neither makes nor loses money. P(x)=0 2.25x-7000=0 2.25x=7000 x=3111.1 Since she can't make 0.1 of a unit, round up to the next whole number. x=3112 units
