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 boxes the girl scout sold. We know from the problem that she sold 392 boxes. So, the part of the percent formula is 392. The whole of the percent formula (the goal number of boxes) is 250. 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 = ^%⁄₁₀₀ ³⁹²⁄₂₅₀ = ^x⁄₁₀₀ Cross multiply and solve for x: ³⁹²⁄₂₅₀ = ^x⁄₁₀₀ 250 * x = 392 * 100 250x = 39,200 250x/250 = 39,200/250 x = 156 So, 392 is 156% of 250.
