D + q = 38......d = 38 - q
0.10d + 0.25q = 6.95

0.10(38 - q) + 0.25q = 6.95
3.80 - 0.10q + 0.25q = 6.95
-0.10q + 0.25q = 6.95 - 3.80
0.15q = 3.15
q = 3.15 / 0.15
q = 21 <== number of quarters

d + q = 38
d + 21 = 38
d = 38 - 21
d = 17 <== number of dimes

If the fourth of 5 consecutive numebrs is 15, what is their sum?
Tju [1.3M]

BRAINLIEST PLEASEEEEEEEEEEEEE

Answer:

70

Step-by-step explanation:

You know the fourth number in this pattern is 15, and that they are all consecutive. With this information you know that the fifth number will be 16, and by counting backwards from 15 you can figure out all of the numbers are 12, 13, 14, 15, and 16. Now, to find the sum of these numbers you must add them together.

This is what it could look like: 12+13+14+15+16

Now to find the answer you need to calculate what the addition would equal, which is 70.

To sell 300 notebooks and 120 pens quickly, a store decided to create two types of gift sets. one set is to include 2 notebooks
VikaD [51]

The store must sell 60 of each set each to obtain the biggest possible income

<h3>How to determine the number of each gift set?</h3>

The given parameters can be represented using the following table:

                        <u>Set 1        Set 2     Available</u>

Notebook         2                3         300

Pen                   1                  1          120

Selling price     8               11.5

Using the above data values, we have:

Objective function: Max P = 8x + 11.5y

Subject to:

2x + 3y ≤ 300

x + y ≤ 120

Next, we plot the graph of the above inequalities (see attachment)

From the attached graph, we have:

(x,y) = (60,60)

Hence, the store must sell 60 of each set each to obtain the biggest possible income
