kotykmax [81]

Answer:

22 cookies

Step-by-step explanation:

A dozen items means 12 number of items.

Number of cookies brought by Sherry = No. of containers multiplied by number of cookies in one container

= 2 \times 6 = 12

Number of cookies brought by Sally = A dozen cookies = 12

Number of cookies brought by Sandy = 2

Number of cookies brought by Sherry, Sally and Sandy together = 12 + 12+2 = 26

Total number of cookies to be brought = 4 dozen = 48 cookies

Number of cookies to be brought by Harry = Total number of cookies to be brought - Number of cookies brought by Sherry, Sally and Sandy together

48 - 26 = <em>22 cookies</em>

sashaice [31]

Answer:

Hi! I suggest reading the explanation, it will help make this equation more simple.

↓↓↓

The answer is $45.50

Step-by-step explanation:

First, divide 26.00 by four. This will give you 6.5, so now you know that each ticket individually costs $6.5 or $6.50.

next, multiple 6.50 by 7.

this will give you 45.5 or $45.50.

double check your answer by dividing 45.50 by 7.

your answer should be 6.5 on a calculator.

that's all! hope this helped.
