we are given
Shanelle purchased a new computer for $1,099
so, cost of new computer =$1099
a computer desk for $699 including tax
so, computer desk cost =$699
now, we can find total cost
total cost =cost of new computer +computer desk cost
total cost =1099+699
total cost= $1798
total months =24
now, we can find monthly payment
monthly payment=(total cost)/(total months)
monthly payment=![\frac{1798}{24}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1798%7D%7B24%7D%20%20)
monthly payment is $74.917.............Answer
