Which shows a correct plan Chuck can use to solve this problem? Chuck brushed his teeth 3 times a day for 4 days. Each time he brushed he spent 30 seconds. He used mint toothpaste for 2 of the days. How many times did Chuck use mint toothpaste?

Answers

Chuck used mint tooth paste 6 times because 4x3 eaquals 12 and 12divided by two is 6 .
The answer is 6 times, because it said he used mint toothpaste for two of the days, and 4 divided by 2 equals 2, and you do the same to the 12 because you did 3 times 4 in the beginning, so you do divided by 2, which equals 6. So to find to the seconds, you do 6 times 30, which equals your seconds, which equals 180 seconds. To find the times he used the toothpaste, you just do 12 divided by 2, which equals 6, so now you know that he used the mint toothpaste six times. 

Answers
Seconds: 180 seconds
Times he used the mint toothpaste: 6 times.

Hope it works!!!

Paul received a $15 tip on a meal that cost $120
What percent of the meal cost was the tip?

Answers

The tippercentage of the meal cost is 12.5%.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The cost of the meal = $120

The amount of tip = $15

The percentage of the tip.

= 15/120 x 100

= 12.5%

Thus,

The percentage of the tip of the meal cost is 12.5%.
