Hello there, you can proceed with the multiplication of these factors using the FOIL method (which stands for first, outer, inner and last) multiply I assume that by descending order, you mean by decreasing power. If it were so, the answer is 6(x^3)12(x^2)-16(x^2)32x-27x+72.

Alexus [3.1K]

Answer:

6 for cherry

19 for blackberry

Step-by-step explanation:

Cherry = x

Blackberry = y

<u>Make system of equations:</u>

Castel:

13x + y = 97

Jasmine:

6x + 3y = 93

<u>Substitution w/ Castel's equation:</u>

y = 97 - 13x

<em>Put into Jasmine's equation</em>

6x + 3(97 - 13x) = 93

6x + 291 - 39x = 93

291 - 33x = 93

-33x = -198

x = 6 $ per Cherry Pie

<u>Plug x = 6 into any equation (choose Castel's):</u>

13(6) + y = 97

y + 78 = 97

y = 19 $ per Blackberry Pie

A pack of cinnamon-scented pencils sells for $8.00. What is the sales tax rate if the total cost of the pencils is $8.64?
vesna_86 [32]
Selling price of a pack of cinnamon scented pencils = $8
Cost of the pack of pencils along with tax = $8.64
Then
Amount of tax taken = (8.64 - 8.00) dollars
                                 = 0.64 dollars
Percentage of sales tax taken = (0.64/8.00) * 100
                                                 = 64/8
                                                 = 8 percent
So the rate of sales tax for the pack of cinnamon scented pencils is 8%. I hope the procedure is clear enough for you to understand. You can use this method for solving similar problems without requiring any help from outside.
