The correct answer for the question that is being presented above is this one: "x = 2; a = 5; b = 3" A 5 inch tall bamboo shoot doubles in height every 3 days. If the equation y=ab^x, where x is the number of doubling periods, represents the height of the bamboo shoot
Answer:
Bob forgot to distribute 3 to 1.50 in the parentheses
Step-by-step explanation:
Bob made the mistake in his first step.
In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.
But, Bob only distributed it to x, which led him to get the wrong answer.
So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50

Original price = x
The original price of a pair of shoes was discounted 20%.
20% = 20/100 = 0.2
1 - 0.2 = 0.8
x * 0.8
Now they sell for $54.
x * 0.8 = 54
Solve to find x.
54 / 0.8 = x
x = 67.5
Convert that to currency.
<h2>$67.50</h2>
3 1/8 = 25/8
25 and 8 have no common factors, so 25/8 is in simplest form.
