1. A bag of 12 oranges costs $2.99. What is the cost per orange?

2. 4 slices of pizza cost $10.50. At this rate, what is the cost of 10 slices of pizza?

3. 4 pieces of candy cost $0.99. At this rate, what is the cost of 7 pieces of candy?

Answers

Answer:

1- $ 0.25.

2- $ 26.25.

3- $ 1.73.

Step-by-step explanation:

1- Given that a bag of 12 oranges costs $ 2.99, to determine what is the cost per orange, the following calculation must be performed:

2.99 / 12 = X

0.249 = X

Thus, the cost of each orange is $ 0.25.

2- Given that 4 slices of pizza cost $ 10.50, to determine what is the cost of 10 slices of pizza at this rate, the following calculation must be performed:

10.5 / 4 x 10 = X

2.625 x 10 = X

26.25 = X

Thus, the cost of 10 slices of pizza is $ 26.25.

3- Given that 4 pieces of candy cost $ 0.99, to determine what is the cost of 7 pieces of candy at this rate, the following calculation must be performed:

0.99 / 4 x 7 = X

0.2475 x 7 = X

1.7325 = X

Thus, the cost of 7 pieces of candy is $ 1.73.

The true statements are (C) After [tex]2[/tex] years the value will be $[tex]605[/tex]  and (E) The value will increase by $[tex]50[/tex] in the first year.

Compound Interest:

Compound interest (or compounding interest) is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

In the first year, the value[tex]=[/tex] $[tex]500+500\times \frac{10}{100}[/tex]

Change in price=$[tex]50[/tex]

After 2 years, the price is=$[tex]550+[/tex]$[tex]550 \times\frac{10}{100}[/tex]

Given:

The measure of an angle is 50 degrees.

To find:

The complement of the given angle.

Solution:

We know that the sum of an angle and its complement is 90 degrees.

Let x be the complement angle of 50 degrees.

[tex]x+50^\circ=90^\circ[/tex]

[tex]x=90^\circ-50^\circ[/tex]
