Alain's mom bought 5 packs of red pens and also bought twice the amount of black pens than the red. If each pack has 5 pens, how many pens does Alain have?
Answer: Alain has 75 pens.
Step-by-step solution
Step 1: Calculate total red pens
Alain's mom bought 5 packs of red pens, and each pack contains 5 pens. To find the total number of red pens, we multiply the number of packs by the number of pens in each pack.
Step 2: Calculate total black pens
The problem states that Alain's mom bought twice the amount of black pens than red pens. Therefore, we multiply the total number of red pens by 2 to find the total number of black pens.
Step 3: Calculate total pens
To find the total number of pens Alain has, we add the total number of red pens and the total number of black pens together.
