Answer 1

After calculating the total cost for each service, Dairy Farms offers a better deal at $52 for 20 gallons of milk compared to Spotted Cow's total cost of $58 for the same amount.

Step-by-step explanation:

To determine which milk delivery service offers a better deal for the ice cream shop using 20 gallons of milk per week, we need to calculate the total cost for each service.

Spotted Cow Service:

Cost per gallon = $2.80

Delivery fee = $2

Total cost for 20 gallons = (20 gallons x $2.80/gallon) + $2 delivery fee = $56 + $2 = $58

Dairy Farms Service:

Cost per gallon = $2.10

Delivery fee = $10

Total cost for 20 gallons = (20 gallons x $2.10/gallon) + $10 delivery fee = $42 + $10 = $52

Comparing the two services, Dairy Farms charges a total of $52 while Spotted Cow charges $58 for the same quantity of milk. Thus, Dairy Farms is the better deal for the ice cream shop.

Answer 2

The Dairy Farm is better deal.

Step-by-step explanation:

Given that:

Per gallon charges of the Spotted Cow = $2.80

Delivery fee = $2

Let,

x be the gallons of milk.

S(x) = 2.80x + 2

Putting x = 20

S(20) = 2.80(20) + 2 = 56 + 2

S(20) = $58

Per gallon charges of the Dairy Farms = $2.10

Delivery fee = $10

D(x) = 2.10x + 10

Putting x = 20

D(20) = 2.10(20) + 10 = 42 + 10

D(20) = $52

Hence,

The Dairy Farm is better deal.
