Answer:
1. The total number of TD stock shares purchases=270
2. The total number of CNA stock shares purchases=450
Explanation:
1. Number of TD stock shares
Step 1: Determine the Total amount invested
Total amount invested=(Cost per TD shareĂ—number of TD shares)+(cost per CNA shareĂ—number of CNA shares)
where;
Total amount invested=$30,150
Cost per TD share=$45
Number of TD shares=x
Cost per CNA share=$40
Number of CNA shares=y
replacing;
45 x+40 y=30,150....equation 1
Step 2: Determine the total dividends in a year
Total dividends=(Expected TD yieldĂ—cost per TD shareĂ—number of TD shares)+(Expected CNA yieldĂ—cost per CNA shareĂ—number of CNA shares)
where;
Total dividends=$936
Expected TD yield=4%=4/100=0.04
Cost per TD share=$45
Number of TD shares=x
Expected CNA yield=2.5%=2.5/100=0.025
Cost per CNA share=$40
Number of CNA shares=y
replacing;
936=(0.04Ă—45Ă—x)+(0.025Ă—40Ă—y)
1.8 x+y=936....equation 2
Step 3: Â Combine equation 1 and 2 then solve simultaneously
Multiply equation 1 by 1;
(45 x+40 y=30,150)Ă—1=45 x+40 y=30,150
Multiply equation 2 by 40;
(1.8 x+y=936)Ă—40=72 x+40 y=37,440
Subtract equation 2 from equation 1;
45 x+40 y=30,150
-
72 x+40 y=37,440
-27 x+0=-7,290
-27 x=-7,290
x=-7,290/-27
x=270
The total number of TD stock shares purchases=270
2. Number of CNA stock shares
Replace the value for x in equation 2 above and solve for y;
1.8 x+y=936
where;
x=270
replacing;
(1.8Ă—270)+y=936
486+y=936
y=936-486=450
y=450
The total number of CNA stock shares purchases=450
