The cost of renting a community center is $100, with an additional cost of $10 per guest. which graph has the most appropriate scales and units for this situation.

The required function is .  The graph of function passing through (0,100) and (-10,0). The x-scale is 1 and the y-scale is 10.

Step-by-step explanation:

The total cost cost function is defined as the sum of fixed cost and variable cost.

Total cost = Fixed cost + Variable cost

From the given information it is noticed that the cost of renting a community center is $100, with an additional cost of $10 per guest.

It means the fixed cost is $100 and the variable cost is $10x, where x is the number of guest.

Total cost function is

where, x is the number of guest.

Put x=0.

The y-intercept is (0,100).

Put C(x)=0,

The x-intercept is (-10,0).

Therefore the graph of function passing through (0,100) and (-10,0). The x-scale is 1 and the y-scale is 10.

maya’s expression will generate the wrong sum because she violated the commutative property.
