A baker is calculating the charge for two types of cookies.

What formula tells the cost, in dollars, if chocolate chip cookies are [tex]$1.50[/tex] per dozen and lemon frosted cookies are [tex]$2.50[/tex] per dozen?

Let [tex]c[/tex] be the number of dozens of chocolate chip cookies, [tex]L[/tex] be the number of dozens of lemon frosted cookies, and [tex]T[/tex] be the total charge.

Click on the correct answer:

A. [tex]T = 4.00(L + c)[/tex]

B. [tex]T = 1.50c + 2.50L[/tex]

C. [tex]T = 150c + 250L[/tex]

D. [tex]T = 2.50c + 1.50L[/tex]

Answer :

To find the correct formula for calculating the total charge for cookies, we need to consider the cost of each type of cookie and the number of dozens being purchased.

1. Chocolate Chip Cookies:
- Cost per dozen: [tex]$1.50
- Let \( c \) represent the number of dozens of chocolate chip cookies.

2. Lemon Frosted Cookies:
- Cost per dozen: $[/tex]2.50
- Let [tex]\( L \)[/tex] represent the number of dozens of lemon frosted cookies.

3. Total Charge Formula:
- The total charge, [tex]\( T \)[/tex], is the sum of the costs for the chocolate chip cookies and the lemon frosted cookies.

Using the costs provided, we can calculate the total charge using this expression:
[tex]\[ T = 1.50 \times c + 2.50 \times L \][/tex]

This formula calculates the total cost based on the number of dozens of each type of cookie purchased.

So, the correct answer is:
[tex]\[ T = 1.50c + 2.50L \][/tex]
