Toby buys a new mp3 player for a price of $45.50. what is the total amount his credit card is charged if the sales tax is 7%?

$45.50 x 0.07= $3.18

$45.50 + $3.18 = $48.68

Hi @Ashvini,

In order to find the amount Toby has to pay we simply need to multiply the price of the product times 0.07.

We do this to determine the sales tax and that is how we calculate the final amount.

Let's start.

45.50 * 0.07 = 3.185

3.185 3.19

We add this amount on the total amount.

Toby would need to pay $48.69.

Thank you for posting this question and let me know if you have any further questions!

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
