It will take them 80 days to sprint 20 miles.
The method that can be used in solving this type of question involves the use of equating fractions together with their arithmetic operation.
<h3>What is a fraction?</h3>
A fraction usually consists of two terms with a term located in the upper part called the numerator and another term located in the lower part called the denominator.
From the parameters given:
- The track team has a plan to sprint 20 miles this school year.
- If the runners participating in the event sprint 1/4 miles in each day.
Then, the estimate of the number of days it will take them to sprint 20 miles can be computed as:
= 80 days

Answer:
1003 in standard form = 1.003 × 1000 = 1.003 × 10^3
Selling price = $46 per toaster
Stocking cost = $28 per toaster
Fixed cost = $2500
a) Let the number of toasters be 'x'
The total cost of stocking for sale = 28x + 2500
b) Let the number of toasters be 'x'
Total revenue received from selling the toasters = 46x
c) Break-even is when the cost of production is equal to profit made
So, we can set up the break-even equation as:
Production cost = Revenue cost
28x + 2500 = 46x
2500 = 46x - 28x
2500 = 18x
x = 138.9 ⇒ Rounded to 139 ovens
Answer:
{x, y, z} = {-4, 2, 4}
