Jenna buys a shirt for $25 and several pairs of pants for $32. Emma buys a jacket for $46 and several pairs of pants for $29 each. Is there a situation which they pay the same amount for their purchases?

• No. The equation has no solution

• There is an infinite number of solutions

• One solution; 5 pairs of pants

• one solution; 7 pairs of pants
