kvasek [131]
<h3>Dan's equation is wrong.</h3>

Step-by-step explanation:

Given, Dan borrows money to buy a new trumpet $400 at simple interest rate of 5% .

{\textrm {simple interest} = \frac{P \times r \times t}{100}      here P =$400,  r = 5% and t = 1

                      =\$\frac{400 \times 5 \times 1}{100}

                      =\$(0.05\times 400)

Therefore he will need to pay back after one year is = 400+(0.05×400)

So, t = 400+(0.05×400)

Dan's equation is wrong.
