Floor tile costs $11 $11 per square yard. How much will it cost to tile a bathroom that is 90 90 square feet?
ira [324]

Answer: $1980

Step-by-step explanation:

Well, based off of the question being asked, I assume that you will need to pay $11 for 90 square footage of tiling, and then the same for the other square footage of tiling. Therefore your answer will be $1980. If you are looking for the equation, it is (<em>11x90)=990   (990)2 = 1980</em>

you do not need to multiply 11 by 90 again because you already know the answer.

Joe Summers buys a gas grill and accessories. The cost, including tax, amounts to $850.00. Joe finances the grill over 12 months
Anettt [7]

Answer:

$66.5

Step-by-step explanation:

The cost, including tax, amounts to $850.00.

Down payment =$150

Amount after paying down payment = $850-$150=$700

Interest rate = 14 %

So, interest on $700 = \frac{14}{100} \times 700 =98

So, c = $98

Total payment = amount financed + c  = 700+98=$798

Now Joe finances the grill over 12 months

So, no. of payments = 12

Now Monthly payment = Total of payments ÷ number of payments

                                        =798 ÷ 12

                                        =$66.5

Hence Joe's monthly payments (principal plus interest) is $ 66.5
