The cost of an ice cream scoop is $11 and the cost of additional toppings is $1.50. Find the cost of an ice cream with 4 toppings.

The correct answer is: Total cost of an ice cream with 4 additional toppings is $17.

Step-by-step solution:-
We are given that-
Cost of 1 ice cream scoop = $11
Cost of each additional topping = $1.50
Let x be the number of toppings and y be the cost of entire ice-cream.
Cost of additional toppings = Cost of each topping × total number of toppings
∴ Cost of additional toppings = 1.50 x .................................................................................................. (Equation i)
Now, we know that-
cost of an icecream = y = Cost of 1 icecream scoop + cost of additional toppings
∴ y = 11 + 1.50 x ........ (From given information & Equation i) ....................... (Equation ii)
Now, we need to find the cost of an icecream with 4 additional toppings.
∴ x = 4
We substitute x = 4 in Equation ii-
y = 11 + 1.50x
∴ y = 11 + 1.50 (4)
∴ y = 11 + 6
∴ y = 17
Final Answer:-
∴ Total cost of an ice cream with 4 additional toppings is $17.
