Answer:

4 sandwiches

Step-by-step explanation:

Since she sold 6 bags of chips, you have to multiply that amount with the price to see the total for that item. Which is 6 x .50=3.

For apple's its 14 x .20=2.80.

And for Juice boxes its 3 x .75=2.25

You then add all of these numbers which gives you the total of 8.05. You now have to subtract that number from 12.05 to get the remaining price for sandwiches since it was not listed.

12.05-8.05=4

4÷1=4

Sorry If I'm not that clear on explaining.

Answer:

4 sandwiches

Step-by-step explanation:

6 bags of chips = $3.00

14 apples = $2.80

3 juice boxes = $2.25

$12.05 total minus $8.05 made from the above items = $4

1 sandwich = $1.00

$4.00 = 4 sandwiches

Joseph and Dwayne are both selling cookie dough for a fundraiser. Although Joseph has already sold 3 tubs, Dwayne hasn't sold an
ArbitrLikvidat [17]

Answer:The number of days it will take to sell the same amount of cookies is 3 and the number of tubs that will be sold is 27

Step-by-step explanation:

Let x represent the number of days it will take either of them to sell the same number of tubs.

Let y represent the total number of tubs that that Joseph will sell in x days.

Let z represent the total number of tubs that that Dwayne will sell in x days.

Joseph has already sold 3 tubs. If Joseph starts selling 8 tubs per day, it means that in x days, the number of tubs that he will sell will be

y = 8x + 3

Dwayne hasn't sold any yet. If Dwayne begins selling 9 tubs per day, it means that in x days, the number of tubs that he will sell will be

z = 9x

To determine the number of days it will take to sell the same amount of cookies, we will equate y to z. It becomes

8x + 3 = 9x

9x - 8x = 3

x = 3

The number of tubs that each will sell will be 9x = 9×3 = 27

HELP ME!!!
larisa [96]

Answer:

  -2, 8/3

Step-by-step explanation:

You can consider the area to be that of a trapezoid with parallel bases f(a) and f(4), and width (4-a). The area of that trapezoid is ...

  A = (1/2)(f(a) +f(4))(4 -a)

  = (1/2)((3a -1) +(3·4 -1))(4 -a)

  = (1/2)(3a +10)(4 -a)

We want this area to be 12, so we can substitute that value for A and solve for "a".

  12 = (1/2)(3a +10)(4 -a)

 24 = (3a +10)(4 -a) = -3a² +2a +40

  3a² -2a -16 = 0 . . . . . . subtract the right side

  (3a -8)(a +2) = 0 . . . . . factor

Values of "a" that make these factors zero are ...

  a = 8/3, a = -2

The values of "a" that make the area under the curve equal to 12 are -2 and 8/3.

_____

<em>Alternate solution</em>

The attachment shows a solution using the numerical integration function of a graphing calculator. The area under the curve of function f(x) on the interval [a, 4] is the integral of f(x) on that interval. Perhaps confusingly, we have called that area f(a). As we have seen above, the area is a quadratic function of "a". I find it convenient to use a calculator's functions to solve problems like this where possible.
