Question

Blue's Berry Farm charges Percy a total of $24.75 for entrance and 2.5 kilograms of strawberries. The entrance fee is $6, and the price for each kilogram of strawberries is constant. The total cost C for picking strawberries is a function of x, the kilograms of strawberries picked. Write the functions formula. C=

Answer 1

Answer:

The cost of each kilogram of strawberries is $7.50.

Step-by-step explanation:

24.75=C

24.75=$6+2.5x

-6        -6

18.75=2.5x

18.75/2.5=2.5x/2.5

$7.5=x

Answer 2

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.
