Answer:
The cost of a bag of chips is
Step-by-step explanation:
Let
c ----> the cost of a bag of chips
we know that
The cost of a juice pouch ($2.50) plus the cost of 3 bags of chips must be equal to $5.05
The cost of 3 bags of chips is equal to multiply 3 by its cost c
so
The linear equation that represent this situation is
solve for c
Subtract 2.50 both sides
Divide by 3 both sides
It will take 16.66years long for the money to double
The formula for calculating the compound amount is expressed as:
A = P(1+r)^t
- A is the amount after t years = 2(900) = $1800
- P is the amount invested = $900
- r is the rate in decimal = 4.25% = 0.0425
Substitute into the formula to have:
1800 = 900(1+0.0425)^t
2 =(1+0.0425)^t
2 = 1.0425^t
ln2 = tln1.0425
t = ln2/ln1.0425
t = 0.6931/0.0416
t = 16.66years
This shows that it will take 16.66years long for the money to double

Answer:
x^4+2x^2y+y^2
Step-by-step explanation:
first we expand the brackets
(x^2+y)(x^2+y)
the it will become
x^4+x^2y+yx^2+y^2
then finally the answer will become
,x^4+2x^2y+y^2
