We can use the percent formula to solve. The percent formula is below: ^part⁄_whole = ^%⁄₁₀₀ First, we have to determine the part. In this problem, the part is the number of donuts that have been sold. We know from the problem that 40 donuts have been sold. So, the part of the percent formula is 40. Remember that the problem tells us that the shop started with 6 dozen donuts. This means we have to determine how many donuts are in 6 dozen. 6 • 12 = 72 total donuts The whole of the percent formula (the total number of accounts) is 72. Now, we have to determine our percent. Since we we don't know the percent, this is where we are going to put our variable (x). ^part⁄_whole = ^%⁄₁₀₀ ⁴⁰⁄₇₂ = ^x⁄₁₀₀ Cross multiply and solve for x: ⁴⁰⁄₇₂ = ^x⁄₁₀₀ 72 * x = 40 * 100 72x = 4000 72x/72 = 4000/72 x = 55.55 So, 40 is 55.55% of 72.
