Answer:
4 treats per dog.
Step-by-step explanation:
Find the rate that she keeps for one dog. As it gives you the rate for 3 dogs, simply divide 3:
(3 dogs/12 treats)/(3/3) = (1 dog/4 treats).
Carol keeps 4 treats for every dog she has.

Answer:
3x - 2y = 1
Step-by-step explanation:
Step 1: Find the slope
slope m = (y2 - y1)(/x2 - x1)
m = (4 - 1)/(3 - 1) = 3/2
Step 1: Use the formula y = mx + b to solve
This is slope-intercept form of a line. We have a slope of 3/2, and a point (x, y), which is (1, 1). Plug those values into the equation above and solve for b (the only variable we are missing
1 = (3/2)(1) + b
1 = 3/2 + b
1 - 3/2 = b
2/2 - 3/2 = b
-1/2 = b
Step 2: Rewrite the formula using the slope and the b value we just calculated
y = (3/2)x - 1/2
Step 3: Standard form of a line is ax + by = c, where a is a positive integer, so we rearrange the equation from step 2 to standard form.
y = (3/2)x - 1/2
-(3/2)x + y = -1/2 (subtract (3/2)x from both sides)
-3x + 2y = -1 (multiply by 2 to get rid of the fraction on x)
3x - 2y = 1 (multiply by -1 so a becomes positive)
Answer to the problem is 18x^4
Her IRA interest at the end of 30 years is mathematically given as

<h3> IRA interest </h3>
Question Parameters:
- N = 30
- PV = 0
- rate = 5%
- FV = 800,000
Generally the equation for the payment function on excel is mathematically given as
A=PMT(rate, nper, pv, [fv], [type])
Therefore, inputting our functions
A=PMT(rate, nper, pv, [fv], [type])
where
A=PMT(5%, 30, 0, [800000], [])
A = 12,041.1481
Hence
interest = 800,000 - 30*12,041.1481
Interest= 438,765.56
