Cm 18) A furniture warehouse is offering a dining room set for a cash price
of plus tax. They also have an instalment plan of 36 monthly

To calculate the after-tax cash price, you’ll first need to know the tax rate. Let’s say it’s 7% (just a common example). The after-tax cash price would be calculated as follows:

After-tax cash price = Cash price + (Cash price × Tax rate)
= .

Total cost = Monthly payment × Number of months
= .

Now, to find the difference between the cash price and the instalment plan cost:

Difference = Total instalment cost - After-tax cash price
= .

So, the after-tax cash price is $ 2675, the total cost using the instalment plan is $ 3060, and the difference is $ 385.

If you’re ever in a similar situation, remember to double-check tax rates, monthly payments, and any additional fees that may apply. It’s a common mistake to overlook these details which can really add to your final cost!
