B) $4
C) $100
D) $200

ANSWER:

D ) $200

It would cost 10 family members a total of $200 to go to the big playland park.

STEP-BY-STEP EXPLANATION:

Let's first establish that the cost of going to the big playland park for a family is given by the following equation.

C = 15x + 50

Where C = total cost of going to the big playland park for a family

Where x = no. of family members going to the big playland park

From this, we will substitute the value given from the problem for ( x ) into the formula to obtain the value of ( C ).

C = 15x + 50

x = 10

THEREFORE:

C = 15 ( 10 ) + 50

C = 150 + 50

C = 200

The cost of going to the big playland park for a family is given by C = 15x + 50, where C represents the cost and x represents the number of family members. How much would it cost for 10 family members to go? A) $3 B) $4 C) $100 D) $200
