<span>The <u>correct answer</u> is:
c(m) = $20 + $0.05m.
Explanation<span>:
To write in function notation, we use a variable, c, to represent cost, and our variable m to represent miles.
Since cost is a function of miles, we write c(m), which we read as "c of m", in place of y.
Everything else in the equation stays the same, as the relationships between the numbers and variables does not change.</span></span>
Capacity of the tank = 45 gallon
At the beginning of Oct., amount of oil in the tank = 45*0.8 = 36 gallons
At the end of Oct., amount of oil in the tank = 45*1/3 = 15 gallons
So, amount of oil used during Oct = (36-15) = 21 gallons

Answer:
1) (1 1/2)(7/5) = g
2) (1 1/2)/(5/7) = g
Step-by-step explanation:
1) Tyler has painted 5/7 of the 7/7 of the fence. So the total amount of the fence is (7/7)/(5/7) = 7/5 as much as what was already painted.
The total amount of paint needed is then 7/5 the amount already used:
g = (7/5)(1 1/2) . . . . . gallons of paint needed for the whole fence
__
2) If g gallons are required for the whole fence, the amount used so far for 5/7 of the fence is 5/7 of the quantity required:
(5/7)g = 1 1/2
g = (1 1/2)/(5/7) . . . . division expression for the paint needed

Answer:
$12 000 in Portfolio 1 and $13 000 in Portfolio 2
Step-by-step explanation:
The formula for simple interest is
I = Prt
For each portfolio, t = 1 yr
For Portfolio 1, i = 5.25 % = 0.0525
For Portfolio 2, i = 4 % = 0.04
Let x = amount invested in Portfolio 1. Then
25 000 - x = amount invested in Portfolio 2 and
25 000 - x = 25 000 - 12 000 = 13 000
So, $12 000 is invested in Portfolio 1 and $13 000 is invested in Portfolio 2.
Check:
OK.
