Question

Tim was paid $1.50 for every toy he sold. He was paid an additional $5 as bonus for every 10 toys sold. He received a
total of $127.50 after selling some toys.
How many toys did he sell?

Answer 1

Let's assume Tim sold x toys.
Tim earned $1.50 for every toy sold, so he earned 1.5x dollars from those toy sales.
He also earned $5 as a bonus for every 10 toys sold, or $5/10 = $0.5 for every toy sold.
Therefore, he earned 0.5x dollars from those bonuses.
The total amount he earned is the sum of these two amounts: 1.5x + 0.5x = 2x dollars.
We know that the total amount he earned is $127.50, so 2x = 127.50.
Dividing both sides of the equation by 2, we find x = 127.50/2 = 63.75.
Since Tim cannot sell a fraction of a toy, we round down to the nearest whole number to find that Tim sold 63 toys. Answer: \boxed{63}.
