Skippy has a total of $10,000 to split between two investments. One account offers 4% simple interest, and the other account off
ki77a [65]

Skippy should invest $ 7500 in account offering 4 % interest and $ 2500 in account offering 8 % simple interest

<em><u>Solution:</u></em>

Given that Skippy has a total of $10,000 to split between two investments

One account offers 4% simple interest, and the other account offers 8% simple interest

Total interest earned = 500

Number of years = 1

Let the principal with rate of interest 4 % is x

So the principal for rate of interest 8 % is 10000 - x

Total interest earned = simple interest for 4 % interest + simple interest for 8 % interest

Simple interest is given as:

S.I = \frac{pnr}{100}

Where "p" is the principal and "r" is the rate of interest and "n" is the number of years

Therefore,

\text{ Total interest earned } = \frac{x \times 1 \times 4}{100} + \frac{10000-x \times 1 \times 8}{100}

500 = 0.04x + (10000 - x)0.08\\\\500 = 0.04x + 800 - 0.08x\\\\-300 = -0.04x\\\\x = 7500

Therefore skippy should invest $ 7500 in account offering 4 % interest

And skippy should invest (10000 - x) = (10000 - 7500) = $ 2500 in account offering 8 % interest

7 - 2x = 2(x - 4) - 1 solve
Naddika [18.5K]

Answer:

x = 4

Step-by-step explanation:

expand out the brackets to get   7 - 2x = 2x - 8 - 1

we can then add 2x to both sides to get        7  = 4x - 8 - 1

add 9 to both sides to get       16 = 4x

divide both sides by 4 to get     x = 4

hope that helps

Mary buys a 10-meter spool of thread for sewing. She uses 210 centimeters. How much is left on the spool in centimeters?
Margaret [11]

100 cm = 1 meter

210 cm = 2.1 meters (multiply both sides by 2.1)

Mary uses 2.1 meters of thread so far, meaning she has 10-2.1 = 7.9 meters left

7.9 meters = (7.9 m)*(100 cm/1 m) = 790 cm

--------------------------------------

Alternate route:

10 meters = (10 m)*(100 cm/1 m) = 1000 cm

Mary uses 210 cm out of 1000 cm total, so she has 1000-210 = 790 cm left.

--------------------------------------

<h3>Answer: 790 cm</h3>
