The sales tax in your city is 8.8%, point, 8, percent, and an item costs $63$, before tax.
PIT_PIT [208]

You would pay $5.54 on that item.

Step-by-step explanation:

Given,

Cost of item = $63

Sales tax rate = 8.8%

Amount of sales tax = 8.8% of cost of item

Amount of sales tax = \frac{8.8}{100}*63

Amount of sales tax = \frac{554.4}{100}

Amount of sales tax = $5.54

You would pay $5.54 on that item.

2x + y = 2<br><br> x – 2y = -4<br><br> what is x and y?
sergiy2304 [10]

Answer:

x = 0

y = 2

Step-by-step explanation:

2x + y = 2 (Multiply by 2)

x – 2y = -4

4x + 2y = 4

x – 2y = -4

5x = 0

x = 0

2x + y = 2

2(0) + y = 2

0 + y = 2

y = 2
