David is buying a cheese wheel priced at \$650$650dollar sign, 650 before tax. The store charges 8\%8%8, percent sales tax.
lozanna [386]

Answer:

$702

Step-by-step explanation:

To find the total price of the cheese wheel that David is buying, we need to multiply the original cost to sales tax first.

Original Cost = $650

Sales Tax Percentage= 8% or 0.08

Now let's solve for how much the sales tax is.

Sales Tax = 0.08 x 650

Sales Tax = $52

Now to get the price including the tax, we simple add the original cost to the sales tax.

Total Price = $650 + $52

Total Price = $702

So the cheese wheel that David bought is $702 with tax included.

IrinaK [193]

The question can be solved as follows:

\frac{5.52\times10^3}{1.2\times10^5}=\frac{5.52}{1.2}\times10^{-2}=4.6\times10^{-2}

Hence the value of the given expression in scientific notation is expressed as:

\frac{5.52\times10^3}{1.2\times10^5}=4.6\times10^{-2}

Larry thought of a number. He added 1, multiplied the sum by 2, divided the product by 3, and then subtracted 4. He got 6. What
antoniya [11.8K]

Answer: Larry thought of the number 14

Step-by-step explanation:

Let the number be represented by x

Such that when added with 1 becomes x+1

Multiplied by 2 becomes 2(x+1)

divided  by 3 gives 2(x+1)/3

Upon subtraction with 4, we have

2(x+1)/3 -4=6 as the equation

Solving

2(x+1)/3 -4=6

2(x+1)/3=6+4

2(x+1)/3=10

2(x+1)=3x10

2(x+1)=30

2x+2=30

2x=30-2

2x=28

x=28/2

x=14
