For given question,
Mira buys a telescope that costs $180.
⇒ Price before tax = $180
sales tax = 4%
Let 'm' be the tax amount.
Using the formula of tax rate,
⇒ Tax rate = (Tax amount ÷ Price before tax) × 100%
⇒ 4% = ([tex]\frac{m}{180}[/tex]) × 100%
⇒ 0.04 × 180 = m
⇒ m = 7.2
Using the formula for the tax amount,
⇒ Tax amount = Final price - Price before tax
⇒ Final price = Tax amount + Price before tax
⇒ Final price = 7.2 + 180
⇒ Final price = $187.2
Therefore, Mira would pay $187.2
