Oscar's T-shirt Shop charges a design fee of $25 plus $15 per shirt for each new order. If Oscar charges the cost per shirt to $20, which of the following representations would accurately describe the situation? I. The difference between the rate of change for the new cost structure and rate of change for the old cost structure is $5 per shirt. II. The equation y=25x+20 represents the relationship between the total cost of the order, y, and the number of shirts, x, in the new cost structure. III. The graph below represents the new cost structure.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

the answer is 13/48

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
