Jamaal buys his clothes at Super Discounts. On Saturday, he bought shoes regularly priced at $40 for 25% off, and a jacket regularly priced at $100 for 30% off. Including a 6% sales tax, what total amount will Jamaal pay? 

Answers

100-25=75%

$40-100%
$ x -75%

100x=3000
x=$30

100-30=70%

$100-100%
$ y - 70%

100y=7000
y=$70

total: x+y=70+30=$100

+ sales tax
100% +6%=106%

$100-100%
$ z - 106%

10600=100z
z=$106

Answer: Jammal will pay $106.

He would pay $30 for the shoes, and $70 for the jacket.

So, in total 106.

Payton collected data to show the relationship between the number of hours he practices and the number of errors he makes when playing a new piece of music. The table shows his data. A 2-row table with 9 columns. The first row is labeled number of hours with entries 1, 2, 3, 4, 5, 6, 7, 8. The second row is labeled number of errors with entries 36, 34, 30, 31, 23, 16, 11, 5. Which is the approximate slope of the line of best fit for the data? –5.5 –4.5 –2.0 –1.0

Answers

The approximate value of the line of best fit which is the ratio of the change in y and the change in x axis from the options given is -4.5.

The slope of the line of best fit can be determined using the following pair of points :

(1, 36) and (8, 5)

x1 = 1 ; x2 = 8; y1 = 36 ; y2 = 5

The slope is defined thus :

  • Slope = (y2 - y1) ÷ (x2 - x1)

Substituting the values into the equation :

Slope = (5 - 36) ÷ (8 - 1)

Slope = -31 ÷ 7

Slope = - 4.428

Therefore, the nearest option from the options given is - 4.5. Hence, the approximate value of slope the best fit line is - 4.5

A jar holds 16 ounces of honey. A cook is going to make two recipes. One calls for 2.5 ounces of honey, and the other calls for 4.25 ounces of honey. After the cook has made those two recipes, how many ounces of honey will be left in the jar?

Answers

The amount of ounces of honey that will be left in the jar is 9.25 ounces.

How many ounces of honey will be left in the jar?

To find out how many ounces of honey will be left in the jar after making the two recipes, we need to subtract the total amount of honey used in the recipes from the initial amount of honey in the jar.

The first recipe calls for 2.5 ounces of honey, and the second recipe calls for 4.25 ounces of honey. Therefore, the total amount of honey used in both recipes is:

2.5 ounces + 4.25 ounces = 6.75 ounces

Now, to determine howmany ounces of honey will be left in the jar, we subtract the total amount used from the initial amount:

16 ounces - 6.75 ounces = 9.25 ounces

After making both recipes, there will be 9.25 ounces of honey left in the jar.
