Answer:
a = 7
Step-by-step explanation:
8a - 4 = 3 + 7a export like terms to the same side of the equation
8a - 7a = 3 + 4 add like terms (the expressions will change sign when exported like when it's a negative expression it will be positive and vice versa.)
a = 7
Answer:

Step-by-step explanation:




The equation that could be used to represent this relationship is... c = 20f
If 50 people attended, Hanks cost would be... $1000... because...
- c = 20 x 50
- 1000 = 20 x 50
So, it will be $1000 for the party, if 50 people come to the party.

Answer:
The principal amount necessary to fund is $573.31
Step-by-step explanation:
Given as :
The quarterly withdrawal amount = A = $850
The time period for withdrawals = t = 9 years
The rate of interest = r = 4.4% compounded quarterly
Let The principal amount necessary to fund = $p
Now, <u>From Compound Interest</u>
Amount = Principal × 
Or, $850 = p × 
Or, $850 = p × 
Or, $850 = p × 
Or, $850 = p × 1.4826
∴ p = 
i.e p = $573.31
So,The principal amount necessary to fund = p = $573.31
Hence, The principal amount necessary to fund is $573.31 Answer
