Answer:
$6898.50
Step-by-step explanation:
Cost price of one book = $10.95
Question says 630 friends bought her books.
And asks for total sales she made.
So we multiply cost of one book with the number of customers , it will give us the total sales.
So
Total sales = $10.95 * 630 = $6898.50
Total sales = $6898.50
Answer:
91%
Step-by-step explanation:
The answer should be $650 because, $100 a day for five days is $500. Then the overtimes for three days would equal up to $150 in overtime. $500 + $150 = $650
Answer: $12
explanation:
we know that 2 CDs and 6 DVDs cost $156 and 1 CD and 9 DVDs cost $210.
this gives us the equations:
2x + 6y = 156
and
1x + 9y = 210
where x is CDs and y is DVDs
multiply the top equation by 9 and the bottom by -6 to solve for x:
18x + 54y = 1404
-6x - 54y = -1260
add from top to bottom:
12x = 144
divide both sides by 12 to get:
x= $12
Answer:
A boxplot offers us information that can be used to compare two variables. In particular, if one variable is quantitative and the other variable is qualitative, a boxplot is generated for each category of the qualitative variable. Therefore, through this graph it is possible to analyze the relationship between the amount of money spent on food and the gender of the person.
A circular diagram offers information for a single variable, especially of a qualitative type.
A histogram offers us information for a single variable, especially quantitative type.
A relational analysis between two variables could be done using options (D) or (E), however one of the variables of interest is of qualitative type and the other is of quantitative type, so the scatterplot and the two-way table.
