Jen's bill at a restaurant before tax and tip is $22. if tax is 5.25% and she wants to leave 15% of the bill before the tax for a tip, how much will she spend in total.

She will spend a total of $26.6285

Step-by-step explanation:

Step 1: Determine the initial bill before tax and tips

Initial bill=$22

Step 2: Calculate the amount of the tax

Tax amount=5.25% of the initial bill

where;

initial bill=22

tax amount=(5.25/100)×22=1.155

replacing;

Tax amount=(5.25/100)×22=1.155

The tax amount=$1.155

Step 3: Calculate the subtotal after taxes

The subtotal can be expressed as;

Subtotal=tax amount+initial amount

where;

tax amount=$1.155

initial amount=$22

replacing;

Subtotal=(22+1.155)=23.155

Subtotal=$23.155

Step 4: Calculate total bill include tips

Total bill=subtotal+15% of subtotal

Total bill=23.155+(15/100)×23.155

Total bill=$26.6285

She will spend a total of $26.6285

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
