Answer:

For the item that costs %58, he should pay $4.06 as sales tax.

Step-by-step explanation:

Let x% be the sales tax.

So, x% of 42 = 2.94.

[tex]\frac{x}{100}[/tex] × 42 = 2.94

x = 2.94 × [tex]\frac{100}{42}[/tex]

= 7

So, 7% is the sales tax.

Now, 7% of 58 = [tex]\frac{7}{100}[/tex] × 58

= 4.06
