Question

What is the total cost a $12.50 item plus 8% sales tax?

Answer 1

Answer:

The total cost is: $13.50              

Step-by-step explanation:

Given

Item cost = $12.50

Sales tax = 8% = 0.08

To determine

Total cost = ?

Sales amount can be calculated by multiplying item cost 12.50 by sales tax 8% or 0.08.

Sales amount = Item cost × 0.08

                       = 12.50 × 0.08

                       = $1

The total cost can be calculated by adding the item cost plus the Sales amount.

Total cost = Item cost + Sales amount

                 = 12.50 + 1

                 = $13.50

Therefore,

The total cost is: $13.50                  

Answer 2

Answer:

$13.50$$

Step-by-step explanation:

$\frac{x}{12.50} = \frac{8}{100}$

$(x)100 = (8)12.50$

$(x)100 = 100$

$\frac{(x)100}{100} = \frac{100}{100}$

$x = \frac{100}{100}$

$x = 1$

$12.50 + 1 = 13.50$

$13.50$$
