A. p = 8n - 30
Each item n is $8.
Expenses totaling $30 are subtracted.

So if the profit (p) is $170.00,
170 = 8n - 30

Now you need to solve.
Add 30 to both sides.

200 = 8n
Divide both sides by 8.

25 = n

25 items were bought.

b. If 25 items were bought, but the expenses were instead $40, what would be the total profit?
p = 8(25) - 40
p = 200 - 40
p = 160

The profit decreased by 10.

il63 [147K]

Answer:

Step-by-step explanation:

We need to use BODMAS to figure out the answer to this extremely difficult question:

So first we need to multiply:

-7 × 6 = -42

Then we need to add:

2 + 4 + 5 = 11

Now we need to subtract:

11 - 42 = -31

2)4

3)27

4)126

5)15

Step-by-step explanation:

1. We need to see how many 8-miles are in 24 miles, than multiple it with 2in.

(24/8)*2=3*2=6in

2. Fist we calcue how many 17-feets are in 68feets, and multiple that with 1in.

(68/17)*1=4

3. We first see how many 3ins are in 9ins, and than multiple that with 9feet

(9/3)*9=3*9=27

4. First see how many 2ins are in 36ins, and then multiple it with 7.

(36/2)*7=18*7=126feet

5. See how many 15fts are in 75ft And than multiple it with 3.

(75/15)*3=5*3=15

A 35 foot rope is cut into two pieces with one section 6 times as long as the other section, how is the shorter piece?
guajiro [1.7K]
-------------------------------------------
Define x:
-------------------------------------------
Let the shorter piece be x.
Shorter piece = x
Longer piece = 6x

-------------------------------------------
Construct equation:
-------------------------------------------
x +6x =35
7x = 35
x =5

-------------------------------------------
Find the length:
-------------------------------------------
Shorter length = x = 5 feet
Larger length = 6x = 6(5) = 30 feet

-------------------------------------------
Answer: The shorter piece is 5 feet.
