Okay, the only data in this you need to know is 15 = \frac{20}{100}x, where x is the total cost of dinner. 
Multiply both sides by the reciprocal of the fraction on the right to find the solution. Therefore x = \frac{1500}{20} =  75

$75

Answer:

Step-by-step explanation:

Take 60% of 61.20. That is the markup.

60% * 61.20 = 60/100 * 61.2 = 3672/100 = 36.72

The markup is 36.72

If the circumference is 31.4, what are the radius and the area?
jekas [21]

Answer:

radius = 5 units

area of a circle = 15.7units²

Step-by-step explanation:

given that the circumference of a circle = 31.4

radius = ?

recall that the formulae for finding the circumference of a circle  =  2πr

circumference of a circle  = 2 x 3.14 x r

31. 4 = 6.28r

divide both sides by the coefficient of r which is 6.28

31.4/6.28 = 6.28r/6.28

5 = r

radius = 5 units

therefore the radius of the circle whose circumference is 31.4 units is evaluated to be 5units

to find the area of the circle

recall the formula = πr²

area of a circle = 3.14 x 5²

area of a circle = 3.14 x 25

area of a circle = 15.7units²
