Answer for screen readers
The customer should add $5$ extra units per month to his 12-month budget.
Steps to Solve
-
Calculate Total Extra Units Needed First, we need to find the total number of extra units needed over the three months. This can be calculated as: $$ 15 + 30 + 15 = 60 \text{ extra units} $$
-
Determine the Monthly Extra Units Next, since this total needs to be spread over 12 months, we divide the total extra units by 12 to find out how many extra units should be added to each month’s budget: $$ \frac{60 \text{ extra units}}{12 \text{ months}} = 5 \text{ extra units per month} $$
-
Final Result The result indicates how many extra units should be added each month to accommodate the increase over the budget period.
The customer should add $5$ extra units per month to his 12-month budget.
More Information
This calculation ensures that the customer can cover the spike in orders over the next three months without exceeding their annual budget. By distributing the total extra units across all months, they can maintain a balanced budget.
Tips
- Misadding the Extra Units: Ensure you carefully add the units needed for each of the three months to get the total correctly.
- Wrongly Dividing by the Wrong Period: Remember to divide by 12 months, not by the number of months with extra units, as we are looking for a monthly average over the whole year.
