Answer:
C = 6 + 7.5 x
Step-by-step explanation:
Given,
The amount is $24.75 for entrance and 2.5 kilograms of strawberries.
⇒ Entrance fee + 2.5 kilograms of strawberries = $24.75
Since, Entrance fee = $ 6,
And, the price for each kilogram of strawberries is constant.
⇒ $ 6 + 2.5 × 1 kilograms of strawberries = $24.75
⇒ 2.5 × 1 kilograms of strawberries = 18.75
⇒ 1 kilograms of strawberries = $ 7.5.
Thus, the cost of x strawberries = 7.5 x
Also, the total charge for x strawberries = Entrance fee + the cost of x strawberries
= 6 + 7.5 x
⇒ C = 6 + 7.5 x
Which is the required function formula.
