Dan bought x pounds of potatoes for 0 point 8 5 dollars per pound and y pounds of grapes for 1 point 2 9 dollars per pound. The total cost was less than 5 dollars Which inequality represents his purchase?

Potatoes cost $0.85 per pound, so x pounds cost 0.85x dollars. Grapes cost $1.29 per pound, so y pounds cost 1.29y dollars. Since their combined cost is less than $5, the inequality is 0.85x + 1.29y < 5, which is choice B.
