The greatest common factor is 7.
Answer:
Step-by-step explanation:
As the angles are supplementary, they sum up to 180
Hence, 3x+40+80=180
3x+120=180
3x=60
x=20
$100 - $61
$39 (how much you need for the price to become equal)
$15 - $12
$3 (how much cheaper it is per uniform)
$39/$3
13 uniforms is where it is equal
14 uniforms is where it is a better deal
I=PRT
I=interst
P=invested amount
R=rate in decimal
T=time in years
given
P=680
R=3.5%=0.035
T=6
I=680*0.035*6
I=142.8
that is interest
total is interest+principal=680+142.8=822.8
after 6 years, $822.80 is in the account
