Darina [25.2K]

Answer:

112 tiles

Step-by-step explanation:

Area = 28ft sq

Tiles are 1/4 each sqft

We are working cube square inside cube ft square = 1 sq /4 (for multiplier).

= 4 x 28 = 112

112 x 0.25 = 28 to check.

112 x 0.25 x 4 = 112 is the multiplier to check again.

Assume the rate of inflation is 5​% per year for the next 2 years. What will be the cost of goods 2 years from​ now, adjusted fo
kirza4 [7]
The equation for inflation is
A = P*(1+r)^t
which is an exponential growth equation (if r > 0). If r < 0, then we have deflation.

where...
A = final price after t years
P = initial starting price
r = rate of inflation in decimal form 
t = number of years

In this case, 
A = unknown (we're solving for this)
P = 280 is the starting price
r = 0.05 is the decimal form of 5%
t = 2 years

We will plug these three pieces of info into the formula to get...
A = P*(1+r)^t
A = 280*(1+0.05)^2
A = 280*(1.05)^2
A = 280*(1.1025)
A = 308.70

Answer: 308.70 dollars
