Answer:

1.3

Step-by-step explanation:

BC is the distance between B and C.

BC = x − (-0.4)

BC = x + 0.4

AB is the distance between A and B.

AB = -0.4 − (-1.25)

AB = -0.4 + 1.25

AB = 0.85

Substitute into the equation.

BC = 2AB

x + 0.4 = 2(0.85)

x + 0.4 = 1.7

x = 1.3

Answer:

x=1.3

Step-by-step explanation:

AB=(-0.4-(-1.25))=1.25-0.40=0.85

BC=2AB=2×0.85=1.70

x=-0.4+1.7=1.3

You are at a grocery store and the cost of your groceries is $32.75. You need to add the sales tax, which is 6%. You have one $2
schepotkina [342]

1. The total bill including sales tax is <u>$34.72</u>.

2. The amount the purchaser should pay the cashier is <u>$34.72</u>.

3. The denominations for the payment should be one $20 bill, one $10 bill, four $1 bills, and 72 cents (pennies).

<h3>How is the total cost determined?</h3>

The total cost payable to the grocery store cashier is the cost of the groceries plus the sales tax.

The cost for groceries = $32.75

Sales tax = 6%

Total cost = cost plus sales tax

= $34.72 ($32.75 x 1.06)

We can check the sum as follows:

Unit  Bill  Amount

1      $20    $20

1      $10       10

4       $1        4

Cents           0.72

Total        $34.72

Thus, the grocery purchaser will be spending <u>$34.72</u>, including the sales tax.
