A garden store sells packages of pumpkin seeds for $2.50, tomato seeds for $1.50, and chili pepper seeds for $0.90. Harry is planning to plant three different types of vegetables on his farm.

User
The cost of three packets of pumpkin seeds is 3 x $2.50 = $7.50. The cost of four packets of tomato seeds is 4 x $1.50 = $6. And, the cost of five packets of chili pepper seeds is 5 x $0.90 = $4.50.                                 Therefore, Harry will spend $7.50 + $6 + $4.50 = $18. The answer: 18.
