Answer:

30 and 6

Explanation:

Let the numbers be x and y. Then

<span>x+y=36</span>
<span>x−y=24</span>

Adding the two equations together gives

<span>2x=60</span>

<span>∴x=30</span>

Substituting this back into either of the equations gives <span>y=<span>6</span></span>

Sum means add.
difference means subtract.

x + y = 36
x - y = 24 Just to make it complete, I finish the problem. Add the two equations.
=======
2x = 60 Divide by 2
x = 60/2
x = 30

x + y = 36 Substitute for x
30 + y = 36 Subtract 30
y = 36 - 30
y = 6

So the solution point is (30,6)

Phyllis invested 50000 dollars, a portion earning a simple interest rate of 5 percent per year and the rest earning a rate of 7

Elodia [21]

Answer:

The amount invested at 5% was $39,000 and the amount invested at 7% was $11,000

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

Let

x-----> the amount invested at 5%

50,000-x -----> the amount invested at 7%

so

$t=1\ year\\ I=\$2,720\\r_1=0.05\\r_2=0.07\\P_1=\$x\\P_2=\$(50,000-x)$

substitute in the formula above

$2,720=x(0.05*1)+(50,000-x)(0.07*1)$

solve for x

$2,720=0.05x+3,500-0.07x$

$0.07x-0.05x=3,500-2,720\\0.02x=780\\x=\$39,000$

$(50,000-x)=\$11,000$

therefore

The amount invested at 5% was $39,000 and the amount invested at 7% was $11,000
