Sawyer owns a bicycle shop. during one week, he sells b bicycles for
$125 each. he also sells 3 helmets, which cost $14 each. if sawyer's
total revenue for the week was $917, how many bicycles did he sell?

To find the total revenue for any object, you simply multiply the price of the object by the number of units sold.

In this case, the revenue for helments would be 3*14, and the revenue for bicycles would be 125*b.

Knowing that total revenue was 917, we can form an equation:

125b + 3*14 = 917

125b + 42 = 917

Subtract both sides by 42:

125b = 875

b = 7

Sawyer sold 7 bicycles
