A certain city has a 6% general sales tax. B) What will be the total cost of the purchase?
mr_godi [17]

Answer:

Final price = 1.06x

Step-by-step explanation:

If a city has a 6% general sales tax, then the total cost of any purchase will be the original price of an item plus 6%, as follows:

Final price = (x + 0.06x) = 1.06x

Therefore, the total cost of any purchase is 1.06 where 'x' represents the price of the items without taxes.

I really need help with c,d and e
Zolol [24]

Answer:

Step-by-step explanation:

By using regression line calculator,

Equation of the line of best fit,

c). y = 0.74x + 0.03

Here, x = Number of pints

y = Weight in pounds

d). We have to find the weight of 10 pints of the blueberries,

By substituting x = 10 in the equation,

y = 0.74(10) + 0.03

y = 7.4 + 0.03

y = 7.43 pounds

e). If per pound cost of the blueberries = $2.25

By substituting y = 2.25 in the equation,

2.25 = 0.74x + 0.03

x = \frac{2.22}{0.74}

x = $3.00 per pound

Therefore, cost of 10 pounds blueberries = 3 × 10

                                                                     = $30

Simplify y^-3 <br><br> a.3/y<br> b.1/y^3<br> c.-3y<br> d.-1/y^3
nignag [31]

Answer:

b. \frac{1}{y^3}

Step-by-step explanation:

Here we are given  y^{-3} and are asked to simplify it. We are going to apply the law of exponents which says that

a^{-n}=\frac{1}{a^n}

Hence applying this rule in our problem we get, where a=y and n=3

y^{-3}=\frac{1}{y^3}

Hence our C) Option is correct

PLEASE HELP A store is having a sale on chocolate chips and walnuts. For 5 pounds of chocolate chips and 3 pounds of walnuts, th
Stells [14]

Answer:

Chocolate Chips cost $2.25 and Walnuts cost $3.25 per pound each

Step-by-step explanatChocion:

Let x = cost of pounds of chocolate chip cookies and y = cost of pounds of walnuts.

From the question, we get 5x+3y = 21 and 2x+6y = 24. To solve the equation, we use substitution. From the first equation, we get y = (21-5x)/3. We substitute the y into the second equation to get 2x + 6(21-5x)/3 = 24. This turns out to be 2x+(42-10x) = 24. Adding like terms you should get 42-8x = 24. Solving for x, x = $2.25 per pound. Plugging this into the first equation, we get 5(2.25)+3y = 21. Solving for y, we get $3.25 per pound of walnuts. If we plug in the numbers into the 2 equations, we will get the right total.
