Afriend lent 17,600 to dawn w. monroe, the owner of a comic book store. she repaid the loan at the end of 6 months at 7 1/2% simple interest. what total amount did dawn pay her friend?

Given that the loan was paid using a simple interest model, then the total amount of interest paid was:
I=(PRT)/100
I=interest
P=principle=$17600
R=rate=7.5%
T=time=6/12=0.5 years
thus
I=(17600×7.5×0.5)/100
=$660
Thus the total amount that Dawn paid will be:
Total=Principle+Interest
=17600+660
=$18260

Your answer should be “c” mark me brainliest
