Question

Can u help me with this?​

Answer 1

Answer: Yes. The sales tax is 5% which equals $4.20 for $84

Explanation:

`(0.60)/(12)=0.05\qquad \rightarrow 5\%\\\\\\(1.20)/(24)=0.05\qquad \rightarrow 5\%\\\\\\(1.80)/(36)=0.05\qquad \rightarrow 5\%\\\\\\(2.40)/(48)=0.05\qquad \rightarrow 5\%`

The sales tax rate is proportional for the values in the table.

$84 x 0.05 = $4.20

The sales tax on a purchase of $84 is $4.20
