The sales tax in a town is 9.4%. To calculate the tax you will pay on a $140 purchase, you need to multiply the purchase amount by the tax rate expressed as a decimal.
First, convert the tax rate to decimal form by dividing it by 100. So, 9.4% becomes 0.094.
To find the tax amount, multiply the purchase amount ($140) by the tax rate (0.094):
Tax amount = $140 * 0.094 = $13.16
Therefore, you will pay $13.16 in tax on a $140 purchase.
In the news, it is stated that tuition is expected to increase by 7% next year. To calculate the new tuition amount, we can use two methods:
Method 1:
If we assume that the 7% increase applies to each quarter's tuition separately, we can calculate the increase for one quarter and multiply it by the total number of quarters in a year (four quarters).
The increase for one quarter can be found by multiplying the current tuition amount ($1200) by the 7% increase rate expressed as a decimal:
Increase for one quarter = $1200 * 0.07 = $84
To find the new tuition amount for the whole year, multiply the increase for one quarter ($84) by the number of quarters in a year (four):
New tuition amount = $84 * 4 = $336
Therefore, the tuition for next year, using this method, will be $336 higher than the current tuition amount.
Method 2:
If we assume that the 7% increase applies to the total tuition amount for the year, we can calculate the increase by multiplying the current tuition amount ($1200) by the 7% increase rate expressed as a decimal:
Increase in tuition = $1200 * 0.07 = $84
To find the new tuition amount for the whole year, add the increase in tuition ($84) to the current tuition amount ($1200):
New tuition amount = $1200 + $84 = $1284
Therefore, the tuition for next year, using this method, will be $1284.
