Answer:
$130.84
Step-by-step explanation:
If a 7% sales tax is applied, the cost of the item (including tax) will be 107% of the original price.
To calculate how much Emma can spend if she has $140 cash to spend, divide $140 by 107%:
[tex]\implies \dfrac{140}{107\%}[/tex]
[tex]\implies \dfrac{140}{\frac{107}{100}}[/tex]
[tex]\implies 140 \times \dfrac{100}{107}[/tex]
[tex]\implies \dfrac{14000}{107}[/tex]
[tex]\implies 130.84[/tex]
Therefore, Emma can spend $130.84 on items if there is a 7% sales tax.
