No she is not correct if she said 200+20+23 was the same as 200+40+3 she would have been correct.
Answer: The mechanic who worked 5 hours charged $45 per hour while the mechanic who worked for 15 hours charged $105 per hour.
Step-by-step explanation:
Let x be the rate of mechanic who worked 5 hours
And y, the rate of mechanic who worked 15 hours
Represent the question in an equation
x + y = 150.............. equation 1
5x + 15y = 1800........equation 2
x + y = 150, x = 150 -y
Substitute the value of x into equation 2 to get y
= 5 (150 -y) + 15y = 1800
Then open the bracket
750 - 5y + 15y = 1800
750 + 10y = 1800
10y = 1800 - 750
10y= 1050 (divide both sides by 10)
y = 1050/10
y = 105
Substitute the value of y into equation 1 to get the value of x
x + 105 = 150
x = 150 - 105
x = 45
Therefore, the mechanic who worked 5 hours charged $45 per hour while the mechanic who worked for 15 hours charged $105 per hour.

Answer:
Exponential functions are patterns that get continuously multiplied by some number. It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.
