ANSWER
a. 10%
b. 35%
Step-by-step explanation
The purchase price of the studio apartment is $150,000.
To find the percentage of the purchase price the down payment is, we have to divide the down payment by the purchase price and multiply by 100.
When the down payment is $15,000, the percentage is:
![\begin{gathered} (15000)/(150000)\cdot\text{ 100} \\ =\text{ 10\%} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/r3x6k8swe1gpk5a5s6cvmq01lxgm5dodcc.png)
When the down payment is $52,500, the percentage is:
![\begin{gathered} (52500)/(150000)\cdot\text{ 100} \\ \text{ = 35\%} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/urxv1xwzx02wbzye4rfnxyfp2qp2up5lfb.png)
That is the answer.
