Answer:

$2000 was invested at 5% and $5000 was invested at 8%.

Step-by-step explanation:

Assuming the interest is simple interest.

<u>Simple Interest Formula</u>

I = Prt

where:

  • I = interest earned.
  • P = principal invested.
  • r = interest rate (in decimal form).
  • t = time (in years).

Given:

  • Total P = $7000
  • P₁ = principal invested at 5%
  • P₂ = principal invested at 8%
  • Total interest = $500
  • r₁ = 5% = 0.05
  • r₂ = 8% = 0.08
  • t = 1 year

Create two equations from the given information:

\textsf{Equation 1}: \quad \sf P_1+P_2=7000

\textsf{Equation 2}: \quad \sf P_1r_1t+P_2r_2t=I\implies 0.05P_1+0.08P_2=500

Rewrite Equation 1 to make P₁ the subject:

\implies \sf P_1=7000-P_2

Substitute this into Equation 2 and solve for P₂:

\implies \sf 0.05(7000-P_2)+0.08P_2=500

\implies \sf 350-0.05P_2+0.08P_2=500

\implies \sf 0.03P_2=150

\implies \sf P_2=\dfrac{150}{0.03}

\implies \sf P_2=5000

Substitute the found value of P₂ into Equation 1 and solve for P₁:

\implies \sf P_1+5000=7000

\implies \sf P_1=7000-5000

\implies \sf P_1 = 2000

$2000 was invested at 5% and $5000 was invested at 8%.

In sweden, vat is at 25%. ella buys a hat in sweden for 50 sek( swedish krona). find the vat paid by ella.
V125BC [204]

If Ella buys a hat in Sweden for 50 SEK with 25% VAT, then the VAT paid by Ella is 12.5 SEK

A Value-Added Tax (VAT) is a consumption tax assessed on the value added in each production stage of a good or service

Given,

The price of hat = 50 SEK

VAT =25%

The amount paid as VAT= 50(\frac{25}{100})

=12.5 SEK

Hence, If Ella buys a hat in Sweden for 50 SEK with 25% VAT, then the VAT paid by Ella is 12.5 SEK
