This is a ratio/proportion problem. We know that 5 widgets cost $2,000. So, how many widgets could you buy with $30,000? We can write that as a proportion: 5: 2,000 :: x: 30,000 Step 1: Rewrite the proportion as a fraction. ⁵⁄_2,000 = ^x⁄_30,000 Step 2: Cross multiply. 5 • 30,000 = 2,000 • x Step 3: Simplify. 5 • 30,000 = 2,000 • x 150,000 = 2,000x Step 4: Simplify by dividing both sides of the equation by 2,000. 150,000 ÷ 2,000 = 2,000x ÷ 2,000 75 = x
