The cost of holding a childrens birthday party at a rollerskating rink is a function of n, thr number of people in the party. The cost function, C, can be represented with this set of rules: C(n) = {150, 0 < n < 12 260, 12 < n < 20 400, 20
How much does it cost to have a party with 9 people? What about 20 people?

Graph the function on the coordinate plane.

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
