We can see that the difference is 8 so we can write:

All you need to do is divide $14 by 25 to find the unit price !
Or in other words, dvide the total price by the total amount of units
14 / 25 = 0.56
This means it is about $0.56 per unit!

Answer:
x = 59
y = 32
Step-by-step explanation:
x + 78 + 43 = 180
x = 59
y + 59 + 89 = 180
y = 32
Zero of 7 with a multiplicity of 3 means one factor is 
Zero of -1 with a multiplicity of 2 means one factor is 
Zero of 5 with a multiplicity of 1 means one factor is 
Multiplying, we get

That's already in factored form so we leave it here.
I guess you want to know the total amount after one year. If so, the interest yielded after one year is 350 x 4% = $14 and her new capital becomes
350 (initial capital) + 14 (interest over 1 year) = 350+14 = $364
