Let B be the price per pound of groundbeef, in dollars. Then the price per pound for steak is (B+5) dollars. 6 lb of steak cost 6*(B+5) dollars. 20 lb of groundbeef cost 20*B dollars. An equation for the total is 6*(B+5) + 20*B = 82 dollars. Simplify and solve for B : 6B + 30 + 20B = 82 26B = 82 - 30 = 52 B = 52/26 = 2 dollars. Answer. The price per pound of groundbeef is $2; the price per pound of steak is 2+5 = 7 dollars. Check. 6*7 + 20*2 = 82 dollars. ! Correct !
