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
Input 10 for x
C=15(10)+50
C=150+50
C=200
The cost is D) $200
