To solve this problem, we'll go through the steps necessary to calculate the discount Nadia receives for ordering 15 packs of elastic bands.
1. Calculate the Total Cost:
Nadia orders 15 packs, and each pack costs £1.59.
So, the total order cost is:
[tex]\[
\text{Total cost} = 15 \text{ packs} \times £1.59 \text{ per pack} = £23.85
\][/tex]
2. Determine the Discount Rate:
Next, we need to check the total cost (£23.85) against the discount bands provided:
[tex]\[
\begin{align*}
£20 \leq £23.85 < £35 & \Rightarrow \text{ Discount rate } = 2.5\%
\end{align*}
\][/tex]
According to the discount bands, for a total cost between £20 and £34.99, the discount rate is 2.5%.
3. Calculate the Discount Amount:
The discount amount can be calculated by applying the discount rate to the total cost:
[tex]\[
\text{Discount amount} = £23.85 \times 0.025 = £0.59625
\][/tex]
4. Final Answer:
The amount of discount Nadia gets is:
[tex]\[
£0.59625
\][/tex]
So, Nadia receives a discount of £0.59625 when she orders 15 packs of elastic bands.
