Calculate the total cost of a jacket at 55.80 with a 2.7% sales tax

Answer

Find out the total cost of a jacket at $55.80 with a 2.7% sales tax .

To proof

As given

cost of a jacket at $55.80 with a 2.7% sales tax

2.7% is written in the decimal form

= 0.027

2.7% of the $55.80 = 0.027 × 55.80

                                = $1.5066

Total cost = 55.80 + 1.5066

                  = $ 57.3066

                   = $ 57.31 (approx)

therefore the total cost is $ 57.31 (approx) .

Hence proved

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

r = 78539458390583095803458309458039485093485 or just 3
