1. A system of equations to determine the cost of a bottle of juice, is <u>12x + 2.70 = 15.78</u>.

2. From the equation, x = $1.09.

<h3>What is an equation?</h3>

An equation is a mathematical statement that shows that two values are equal.

A system of equations uses numbers and variables.

<h3>Data and Calculations:</h3>

The cost price of a bag of chips = $2.70

The total cost of snacks = $15.78

The total cost of 12-pack of juice bottles = $13.08 ($15.78 - $2.70)

Therefore, a bottle of juice = $1.09 ($13.08/12)

<h3>Equations:</h3>

Let a bottle of juice = x

Total cost of snacks = $15.78

2.70 + 12x = 15.78

or 12x + 2.70 = 15.78

12x = 13.08

x = 1.09 (13.08/12)

Answer: About 800 thousand

The more accurate value is 807,528 but this is also an approximation.

=======================================================

Work Shown:

$t = \text{number of years since the year 2000}$

$P_0 = \text{population (in millions) in the year 2000}$

$P = P_0(1.2)^t\\\\5 = P_0(1.2)^{10}\\\\5 \approx P_0*6.1917364224\\\\P_0 \approx \frac{5}{6.1917364224}\\\\P_0 \approx 0.80752791444922\\\\P_0 \approx 0.807528\\\\$

That's the rough population of wild pigs (in millions) for the year 2000.

Multiply by $10^6$ to get it in terms of units instead.

$0.807528\times10^6 = 807,528$

There were roughly 800 thousand wild pigs in the year 2000.

There is a swimming pool which has a length of 15 m and a width of 12 m. There is a 2 m wide path around the pool. If the cost o

AnnyKZ [126]

The cost of the path around the swimming pool with length 15m and width 12m is $1,190

<h3>Area of a rectangle</h3>

Length = 15m
Width = 12m

Pathway with 2m wide:

Length = 15m + 2m = 17m
Width = 12m + 2m = 14m

Area of the path = length × width

= 17m × 14m

= 238 square meters

Cost of the path = $5 per square meter

Total cost of the path = 238 square meters × $5

= $1,190
