Example Question #1 : Linear Equations With Time
It takes Daisy 
Let 
Given that she can plant 10 strawberry plants in an hour, Daisy can plant 
If she wants to plant 70 strawberry plants, then she will plant 
Dividing both sides by 10, we find that Daisy will take 
Example Question #2 : Linear Equations With Time
Two joggers start from the opposite end of a 
Let 
By the same logic, we know that the second jogger runs a distance of 
Since we are looking for the point at which the joggers meet up after running from opposite directions, we know that together they will have covered a total of 10 miles. Therefore:
Simplifying the equation:
Example Question #4 : Linear Equations With Time
Jimmy the handyman earns 
Let 
Dividing both sides by 30:
Example Question #1 : Linear Equations With Time
Francine wakes up at 
To solve this problem, you need to create a linear equation. First, you know that it takes two hours total for Francine to get to school. Two hours can also been translated into a hundred and twenty minutes. Second, you know that it only takes her twenty minutes to get ready. Your variable is the time it takes her to get to school.
So:
Therefore, 
Now we convert this back into hours and minutes.
Since 60 minutes is 1 hour it takes Francine an hour and fourty minutes to get to school.
Example Question #1 : Multiplication And Division With Money
Leon bought 
First, let's find the cost of the socks Leon bought.
Then find the total cost of the shirts Leon bought.
Next, find the cost of the pencils. Watch out here because the pencils are priced per 6. There are two 6's in a dozen.
Add these subtotals together to get the answer.
Example Question #41 : Money And Time
Molly bought 
To find the cost of each individual poster, divide the total cost by the number of posters Molly bought.
Example Question #3 : Multiplication And Division With Money
Please choose the best answer for the question below.
If John has 
For this problem, first you have to calculate the interest, and then add it to the toal in the bank account.
To calculate interest, convert the percent into a decimal 1.7% = .017, and multiply it by the total amount. 
round to the nearest cent and you arrive at

Anne worked at a coffee shop, where she made 
To do this problem, first break it into smaller parts. First, let's find Anne's wage as a receptionist:
Then, take her new hourly wage, 
Finally, round to the nearest whole cent, and you get

Francis has to pay 
Break the problem into two parts. First, add up Francis' expenses:
Then, calculate Francis' income:
Finally, subtract his expenses from his income:
