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%

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

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

A new television set was recently purchased for the common room in a Residence Hall for $428.00 including tax. If the tax rate i

prohojiy [21]

The price of the television set before taxes is $400

<h3>How to find the price of the television set before taxes.?</h3>

The given parameters are:

Price after tax = $428.00

Tax rate = 7%

The price of the television set before taxes is calculated as:

Price after tax = Price before tax * (1 + tax rate)

This gives

$428.00 = Price before tax * (1 + 7%)

Express the percentage as decimal

$428.00 = Price before tax * (1 + 0.07)

Evaluate the sum

$428.00 = Price before tax * (1.07)

Divide both sides by 1.07

Price before tax = $400

Hence, the price of the television set before taxes is $400
