Answer:
0.03A + 0.03B = 800
A + B = 20000
Step-by-step explanation:
Let one part A of the total money invested with 3% interest = $A
Therefore, other part B of the money invested with 5% interest = $B
Interest = Principal amount × Rate of interest × Duration of investment
If the duration is 1 year,
Interest = Principal amount × Rate of interest
Return on part A = A × 0.03
Return on part B = B × 0.05
Total return = $800
So the equations will be,
0.03A + 0.03B = 800 -------(1)
Since, total money invested = $20000
Equation will be,
A + B = 20000 -------(2)

Answer:770.64
Step-by-step explanation:
If PLAN A is cheaper than PLAN B then,
P (A) < P (B)
30+0.01t < 20+0.05t (subtract 0.05t from both sides)
29.95-0.04t < 19.95 (<span>subtract 29.95 from both sides)</span>
-0.04t < -10 (<span>divide both sides by -0.04)</span>
t > 250
<span>So plan A is cheaper than plan B when you send more than 250 texts.</span>
Hope it helps.
