how do you set up kids paid $5 and adults paid $8 to go to the carnival 1250 people attended and $7,300 was collected for the night

The system is:

Step-by-step explanation:

The question demands that we set up a system of equation, if kids paid $5 and adults paid $8 to go to the carnival 1250 people attended and $7,300 was collected for the night.

Let 'k' represents the number of kids and 'a' the number of adults that attended the carnival.

We we're given that 1250 people attended the carnival;

This implies that:

if kids paid $5 and adults paid $8 and $7,300 was collected for the night, then

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
