photoshop1234 [79]

Trevor invested $ 4720

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

Given that, Trevor earned $ 826 on account during 2.5% annual interest for seven years

We can simple interest formula

<em><u>The formula for simple interest is given as:</u></em>

\text{ Simple Interest } = \frac{p \times n \times r}{100}

Where,

"p" is the principal

"n" is the number of years

"r" is the rate of interest

Here given that,

Principal = p = ?

rate of interest = r = 2.5 %

number of years = n = 7

Simple interest earned = 826

<em><u>Substituting the values in above formula,</u></em>

826 = \frac{p \times 7 \times 2.5}{100}\\\\82600 = p \times 7 \times 2.5\\\\82600 = 17.5p\\\\p = \frac{82600}{17.5}\\\\p = 4720

Thus he invested $ 4720

Alec is trying to find the surface area of a shoe box. What unit will he use? A) cubic feet B) square feet C) cubic inches D) sq
zysi [14]
The answer to this question would be: <span>D) square inches</span>

In this question, Alex needs to find the surface area of a shoe box. Surface area unit would be represented by "square" because it is 2 dimension. The unit "cubic" is used for volume which was 3 dimension. From here, the option A and C is out because it uses cubic.
The inch unit is better since it was smaller than feet. If you using feet square, the area of the shoe box will be small and it might be less accurate than using inch.
