Sales tax is 55.74 on the punches of a dining room set for 929. find the sales tax

6%

Step-by-step explanation:

The tax rate times the purchase amount equals the amount of tax.

We have the purchase amount ($929) and the amount of tax ($55.74). We are looking for the tax rate. Let the tax rate be x.

tax rate * amount = tax amount

x * 929 = 55.74

929x = 55.74

Divide both sides by 929.

x = 55.74/929

x = 0.06

The tax rate is 0.06 as a decimal number. To write it as a percent,  move the decimal point two places right.

x = 0.06 = 6%

The sales tax rate is 6%

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
