Sam bought 6 pens for an unknown price plus a backpack. If he spent a total of $28.50, write an
equation to find the cost of each pen.

So sam bought SIX pens for a TOTAL of $28.50. we have to figure out how much money each of the six pens cost.

steps:

1. divide the total by the amount of items purchased:

28.50 / 6 = 4.75

and there’s your answer! each pen cost $4.75

steps to check your work:

1. multiply the single cost by the amount of items purchased:

4.75 ( 6 ) = 28.50

Well if you have 20 bats you probably want 20 balls? you don’t have enough context to answer the question.
