Answer:

a = 6

Step-by-step explanation:

Equate the two angles because opposite angles in a parallelogram are equal.

20a+30=17a+48

20a-17a=48-30

3a=18 (divide both sides by 3)

a=6

A table costs $350. There is also a sales tax of 7%. How much does the table cost, including sales tax?

IrinaVladis [17]

Tax
$350x0.07
=$24.50

(0.07 is the 7% tax in decimal form)

Total cost
$350+$24.50
=$374.50

OR

$350x107%
=$374.50

1.07 is the table cost (100%) plus the sales tax (7%)

The table costs $374.50 with tax.
