Answer:
The correct option is A) 13 to 3.
Step-by-step explanation:
Consider the provided information.
The pet store had 6 puppies selling for $104 each and 12 kittens selling for $24 each. Today, only 2 puppies and 8 kittens were left.
6-2 = 4 puppies sale
12-8 = 4 kittens sale
The cost of each puppies is $104.
Cost of 4 puppies:
4×$104=$416
The cost of each kittens is $24.
Cost of 4 kittens :
4×$24=$96
The ratio of sales of puppies to kittens is:
Hence, the ration of sales of puppies to kittens is 13/3.
Thus, the correct option is A) 13 to 3.
Answer:
p = 2
Step-by-step explanation:
Step 1: Write equation
2p + 7 = p + 9
Step 2: Subtract p on both sides
p + 7 = 9
Step 3: Subtract 7 on both sides
p = 2

Answer:
y = 3x +3
Step-by-step explanation:
The slope of the line can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
Using the first two sets of table values, this is ...
m = (9 -6)/(2 -1) = 3/1 = 3
You can find the point-slope equation using the form ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -6 = 3(x -1) . . . . . using the first point in the table
Solving for y gives ...
y = 3x -3 +6 . . . eliminate parentheses, add 6
y = 3x +3
Answer:
80x-460=300
80x=760
Step-by-step explanation:
In order to know which equation is best, you have to add the total expenses the robotics club had.
<u>Expenses:</u>
- box of shirts = $400
- advertising = $60
Let's add: $400 + $60 =<em> $460 </em>
Next, you have to know how many of the shirts were purchased.
Now, let's compute.
- 80x - 460 = 300
- 80x = 300 + 460
- 80x = 760
- x = $9.5
or
- 80x=760
- x = 760 ÷ 80
- x = $9.5
This means that the robotics club has to sell the shirts at $9.5 each in order to have a $300 profit.
