Ace autos sell cars and pay sue each month as follows

Dima020 [189]

Sue's total pay of year will have three parts

1) Fixed Salary for 12 months

one month salary = £1410

so 12 month salary = £1410 x 12 = £16920

2) 26% of total profit

Total cost to the company- £473,500

Total income for the company - £549,000

Profit = Total income for the company - Total cost to the company

= £549,000 - £473,500 = £75500

Sues income from profit = 26% of £75500 = (26 × 75500)/100 = £19630

3) Bonus if Sue sells at least 16 cars

Given number of months when sue solds atleast 16 cars = 4

So bonus income = 4 × 390 = £1560

Adding the three above parts

Sue's total pay for the year = £16920 + £19630 + £1560 = £38110

Answer:

Radius: 8

Circumference: 50.27

πr^2 = Area of circle

201.06 = πr^2

divide by pi

201.06 / π = 63.9993857161 = 64

64 = r^2

Square root both sides to get radius.

$\sqrt{64}$ = 8

r = 8

Circumference = π x diameter

Diameter = 2 x radius

Circumference = π x 16 = 50.2654824574 = 50.27
