Noah and James are each paid $15 per hour. However, this week Noah received a $60 bonus. Given that N and J represent the number of hours worked by Noah (N) and James (J), which expression can be used to represent their combined earnings for the week?

15N+15J+60

Step-by-step explanation:

We know that Noah and James each receive $15 per hour. That means that to get the money one of them earned in a week, we multiply the money they earn ($15) by the hours they worked (N or J):

15 × N is what Noah earned.

15 × J is what James earned.

Combining those are just 15N + 15J. Then, we add the bonus Noah received ($60) to get their total combined earnings:

15N+15J+60

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
