Explanation:
Let's start by setting up an equation to represent the information given in the problem:
Let x be the price of the hot tub that Randy really wants.
According to the problem, this price is one-fifth (or 1/5) more expensive than Randy's maximum budget of $4,500:
x = 4,500 + 4,500/5
x = 5,400
However, Randy decides to buy a second-hand hot tub that costs $1,225 less than the one he wanted. So the price of the second-hand hot tub is:
x - 1,225 = 5,400 - 1,225
x - 1,225 = 4,175
Therefore, Randy spends $4,175 on the second-hand hot tub.
Explanation:
Step one: 116 * 2 = 232
Step two: 232 / 8 = 29
Explanation:
The first step is to divide each pair of integers in half. As a result, 4 is equal to 8 divided by 2, and 2 divided by 4 is equal to 1/6.
Explanation:
Phase one: 15,006 + 105 – ? = 457
Phase two: ? = 15,006 + 105 – 457
Phase three: ? is 14,654
Explanation:
The formula is x 1, x 4, x 8, x 12, x 16, meaning that each number is multiplied by four more times than the one before it.
Explanation:
Phase one: He has 18 classes but didn’t attend 2, meaning that he only attended a total of 16 classes that week.
Phase two: ¼ of 16 = 4 classes where he was late
Phase three: Convert this to a percentage = 25%
