Answer 2

Answer:

$\huge\mathfrak{answer!}$

rate = 4%

principal = 750

amount = 900

$amount \: = \: principal + \: interest$

amount = 900-750= 150

so interest is 150

$time = \frac{interest}{rate} \times \frac{100}{principal}$

$time = \frac{150}{4} \times \frac{100}{750} = \frac{25}{5} = \\ \: 5 \: years$
