Last week, the Glee Club made 437 flowers. They made 322 more this week than last week. So this could be shown in this case as 437 + 759 (since 437 + 322 = 759). This equals 1,196 flowers. To find the remaining number of required flowers, we could represent this equation as 1,196 + x = 1,250, with x representing the number of flowers still needed. Since 1,250 - 1,196 = 54, they still need to make 54 paper flowers for their parade float. Substituted back into the equation, it would look like this:
1,196 + 54 = 1,250.
