Hey John

Let's start solving #1

x/4 = 3.5/28
Cross multiply
(x)(28) = (3.5)(4)
28x = 14
Divide both sides by 28
28x/28 = 14/28
x = 1/2

Next, let's solve the second one

$\frac{3}{5} + \frac{4}{5x} + \frac{7}{10x} + 1 \frac{1}{2} = 5 \frac{3}{5}$
Simplifies to:
$\frac{105x+75}{50x} = \frac{28}{5}$
Cross multiply
(105x + 75)(5) = (28)(50x)
525x + 375 = 1400x
Subtract 1400x to both sides
525x + 375 - 1400x = 1400x - 1400x
-875x + 375 = 0
Then subtract 375 from both sides
-875x + 375 - 375 = 0 - 375
-875x = -375
To find x, divide both sides by -875
-875x/-875 = -375/-875
x = 3/7

Let me know if you have questions about the answer.

Best of luck with your studies!

1. An equation for income, I = 3c + 2p, where c is the number of calendars sold and p is the number of posters sold.

2. When 25 calendars and 18 posters are sold, the income is $111.

3. Income for selling 12 calendars and 15 posters is $66.

4. 3 possible combinations; 1) 30 calendars and 5 posters. 2) 20 calendars and 20 posters. 3) 10 calendars and 35 posters.

Step-by-step explanation:

Step 1; It is given that each calendar costs $3 and each poster costs $2. So if c is the number of calendars sold and p is the number of posters sold.

Total income, I = 3c + 2p.

Step 2; Now if we substitute the value of c with 25 and p with 18, we get

I = 3c + 2p = 3 (25) + 2 (18) = 75 + 36 = $111.

Step 3; If the value of p is 12 and the value of c is 15, we have

I = 3c + 2p = 3 (12) + 2 (15) = 36 + 30 = $66.

Step 4; To find combinations that cost $100, we substitute I with 100. So the equation becomes 3c + 2p = 100.

When c = 30, 3 (30) + 2p = 100, 2p = 100 - 90 = 10, 2p = 10, p =5.

When c = 20, 3 (20) + 2p = 100, 2p = 100 - 60 = 40, 2p = 40, p = 20.

When c = 10, 3 (10) + 2p = 100, 2p = 100 - 30 = 70, 2p = 70, p = 35.

D 288 because 216/3 equals 72 times that by 4 and you get 288.
