The total amount of money Sandra paid for a slice of pizza with a side salad including tax is $10.089
<h3>How to find total price including tax</h3>
- Price of slice of pizza with a side salad = $9.50
- Tax = 6.2%
Total amount Sandra paid = Price of slice of pizza with a side salad + (Tax × Price of slice of pizza with a side salad)
= 9.50 + (6.2% × 9.50)
= 9.50 + (0.062 × 9.50)
= 9.50 + 0.589
= $10.089
Therefore, the total amount Sandra paid is $10.089

Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40
Step-by-step explanation:
the angle ABC = 180 - x, as ABD and ABC are complementary angles on top of the bottom line : all angles around a point on one side of a line are always adding up to 180 degrees.
but because we also know that the sum of all angles in a triangle is 180 degrees too, we can say
180 = ACB + ABC + CAB
180 = y + 180 - x + CAB
0 = y - x + CAB
x = y + CAB
x - y = CAB
therefore, the second answer option is correct.
