Answer:Suppose the cost stock is x and the cost of fund is y.
Total cost of Nora's portfolio:
100x+200y=3800.....i
Total cost of Erin's portfolio
300x+50y=5350...ii
solving the simultaneous equation by elimination method we proceed as follows:
multiplying eqn by 3 and subtracting ii we get:
550y=6050
thus
y=6050/550
y=11
next, multiply ii by 4 and subtracting i we get:
1100x=17600
x=16
thus the cost of Technology stock was $16 and the cost of mutual fund was $11

Answer: sorry I'm doing a competition for who ever reaches 1k points
When you divide a variable with an exponent by a variable with an exponent, you subtract the exponents (only if the bases/variables are the same)
For example:
Since they have different variables (x and y), you can't simplify this anymore
( if the exponent happens to come out negative, you have to move the variable and the exponent to the other side of the fraction to make the exponent positive)
Ex:
SInce they all have a common factor of 4, you can divide out -4
If you follow the steps from ^^^^^^^, you should get
