Adam is selling tickets for a concert in the park. an adult ticket costs $8.50 and a child ticket costs $5.00. adam sells x adult tickets and 15 child tickets. which function ƒ(x) can be used to determine how much money adam collected from selling tickets? a) ƒ(x) = 8.50x + 5(15) b) ƒ(x) = 8.50 + 5(15)x c) ƒ(x) = x(8.50 + 5(15)) d) ƒ(x) = 8.50x + 5(15)x

Answer is A

Step-by-step explanation:

A) ƒ(x) = 8.50x + 5(15)

Step-by-step explanation:

the total money collected of the tickets is going to be the sum of the money collected by adults and the money collected by children.

The total money collected by adult tickets can be calculate as the multiplication of the unit cost of the tickets for adults and the total number of adults. So,

Adult cost = $ 8.50 * x

Where x is the number of adults who buy a ticket.

Additionally, The money collected for child tickets can be calculate as the multiplication of the unit cost of the child tickets and the total number of children. So,

Child cost = $ 5.00 * (15)

Finally, we are going to call f(X): the total money collected for the tickets. Then,

f(x)=$8.5x+5(15)

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
