Number of cars washed by the eight teams per hour = 2 * 8 = 16 cars.

Answer:
2 weeks
Step-by-step explanation:
Given in the question that,
Equation that represent Lisa's total amount of money
f(x) = 20 - 13x
Equation that represent Joey's total amount of money
g(x) = x² - 10
To find weeks, x, after which they will have same amount of money, we will equate both equation
<h3>20 - 13x = x² - 10</h3>
x² - 10 - 20 + 13x = 0
x² - 30 + 13x = 0
x² + 13x - 30 = 0
(x - 2)(x + 15) = 0
x = 2 or x = -15
Weeks, x, can not be negative so we will reject x = -15
Hence, after 2nd week Lisa and Joey will have the same amount of money save.
<em>A compound number is a number that has more than one factor. A prime number is a number that only has a factor 1, and itself. For example, 17 is a prime number because on 1×17 will give you that. 24 is compound or composite because many factors like 1 and 24 or 2 and 12 or 6 and 4 multiply together to get that number.</em>
