Answer: 187.5 cups of sauce in total
Step-by-step explanation: easy multiply 27 by 7.5
$0.03+$0.04=$0.15x4=$0.60
Answer:
4,218.75
Step-by-step explanation:
Lets say that P is your starting principal (spelled -pal and not -ple, because Your Money is Your Pal), r is the interest rate (expressed as a decimal), and Y is the number of years you invest. Then your future value will be:
P (1 + rY) (Simple Interest)
P (1 + r)Y (Annually Compounded Interest)
Note the two formulas give the same answer for one year. After that, compound interest takes off.
Let
x---------> the length of the first piece
y---------> the length of the second piece
z---------> the length of the third piece
we know that
x+y+z=72 -------> equation 1
y=x+6 -----> solve for x
x=y-6 -------> equation 2
z=6+y -------> equation 3
substitute equation 2 and equation 3 in equation 1
[y-6]+y+[6+y]=72
3y=72
y=(72/3)=24 in
<u>Find the value of x</u>
x=y-6 -------> equation 2
x=24-6=18 in
<u>Find the value of z</u>
z=6+y -------> equation 3
z=6+24=30 in
therefore
<u>the answer is</u>
the length of the first piece is 18 in
the length of the second piece 24 in
the length of the third piece is 30 in
