Answer:

Total amount in Joe's savings account T = $448

Step-by-step explanation:

Given;

time t = 3 years

Annual rate r = 4%

Principal P = $400

Simple interest can be expressed as;

I = Prt/100

Substituting the given values;

I =400×4×3/100 = 4800/100

I = $48

Total amount in account T;

T = P + I = $400 + $48 = $448

Answer:

$448

Step-by-step explanation:

To calculate Joe's savings, we can use the formula for simple interest:

P = Po*(1+r*t)

Where P is the final value, Po is the inicial value, r is the interest and t is the time in years.

So, In our problem, we have that Po = 400, r = 4% and t = 3, then we can find P:

P = 400*(1+0.04*3)

P = 400*1.12 = $448

Joe has $448 in his savings.

Solve for y in x+0.25y=1.5
IRISSAK [1]

Answer:

Y=-4x+6

Step-by-step explanation:

Step 1: Add -x to both sides.

X+0.25y+-x=1.5+-x

0.25y=-x+1.5

Step 2: Divide both sides by 0.25.

0.25y/0.25=-x+1.5/0.25

Y=-4x+6

Hope I helped
