Answer:
With $30, Peter can afford 5 hours
Step-by-step explanation:
Given
Insurance Charge = $7.5
Charges = $4.5 per hour
Required
Determine the number of hours $30 can afford
First, we need to determine the equation.
<em>Total Charges = Charges per hour + Insurance Charge</em>
Substitute values for Charges per hour and Insurance Charge
Total Charges = 4.5 per hour + 7.5
Let the number of hours be n;
So,
Total Charges = 4.5n + 7.5
To calculate Peter's; substitute 30 for total charges
Subtract 7.5 from both sides
Divide both sides by 4.5
Hence;
<em>With $30, Peter can afford 5 hours</em>
Answer:
Step-by-step explanation:
To find many more pounds of apples Kimane and his friend needs to get, we first need to find out how many pounds of apples they picked together.
Kimane =
Friend =
We add them together to find out how many pounds of apples they currently have.
Total Pounds =
Just to make the equation clearer, we separate the whole numbers from the fractions.
Now since we cannot add the 2 fractions directly since they have different denominators, we need to convert the into a fraction with the same denominator.
We multiply both the numerator and denominator by 2 to have the same denominator.
So now we have:
Now that we know how many pounds Kimane and his friend collected, we simply subtract 20 and the total amount Kimane and his friend had already collected.
So Kimane and his friend still need to get more pounds of apples to get 20 pounds of apples.
