Answer for screen readers
The total payment Sarah needs to make is $405$.
Steps to Solve
- Calculate the Total Price Before Discount
First, we need to find the total cost of the 3 shirts. Since each shirt costs $150$, we can calculate the total price as follows:
$$ \text{Total Price} = 3 \times 150 = 450 $$
- Determine the Discount Amount
Next, we need to calculate the 10% discount on the total price. The discount can be calculated by multiplying the total price by 10%:
$$ \text{Discount} = 0.10 \times 450 = 45 $$
- Subtract the Discount from the Total Price
Finally, to find out how much Sarah needs to pay after applying the discount, we subtract the discount from the total price:
$$ \text{Total Payment} = 450 - 45 = 405 $$
The total payment Sarah needs to make is $405$.
More Information
Sarah receives a 10% discount on her total shirt purchase, which helps her save $45$ off the original price. Discounts are commonly applied in retail to encourage purchases.
Tips
- Misapplying the discount: Some may incorrectly think that multiplying the total price by 10% gives the final amount rather than the discount.
- Not calculating the total price first: Skipping the calculation of the total price can lead to incorrect discount calculations.
