The manufacturer's price for a cooler is $28.50. A camping store that buys the coolers sells them for $40.76. What is the approximate percent of increase in the price of the coolers?

43%

Step-by-step explanation:

(40.76 - 28.50) / 28.5 = .43 or 43%

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
