An ice cream truck began its daily route with 95 gallons of ice cream. the truck driver sold 78% of the ice cream. how many gallons of ice cream were sold

74.1 gallons

Step-by-step explanation:

An ice cream truck started its daily route with the amount of ice cream = 95 gallons

The truck driver sold the amount of ice cream = 78% of 95 gallons

The amount of ice cream were sold = 78% × 95

                                                            =

                                                            = 0.78 × 95

                                                            = 74.1 gallons

74.1 gallons of ice cream were sold.

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
