Question: Peter has $70 and wishes to spend an equal amount each day for one week. From Sunday through Wednesday, he spent his money on wooden action figures which cost $5 each. For the rest of the week, he will buy plastic action figures which cost $2 each. How many total action figures will he have by the end of the week?
Work out the solution step by step. 
Answer: 
There are 7 days in a week so if he wishes to spend an equal amount of $70 each day that would be $70/7 = $10
For four days (Sunday through Wednesday) he will spend 4*$10 = $40
He will spend $40 on wooden action figures of $5 each which gives $40/$5 = 8 wooden action figures
For the remaining 3 days he will spend 3*$10 = $30
He will spend $30 on plastic action figures of $2 each which gives $30/$2 = 15 plastic action figures
Altogether, he will have 8+15 = 23 action figures.
