Five friends went to an amusement park. The cost of admission per person is x dollars. Three friends paid $30 each for a front-of-line pass. The group had a $20 coupon off the total price. Circle all of the expressions that represent the total cost.

5x + 30 – 20. 3(30) + 2x – 20. 5(x + 30) – 20. 5x + 70

2x + 70. 3(x + 30) + 2x – 20. 3(x + 30 – 20) + 2x. 5x + 10

3(x + 10) + 2x. 3x + 30 + 2x – 20. 3x + 90 + 2x – 20 5x + 30

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

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

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
