Answer:
$64
Explanation:
We have been given that an item regularly priced at $80 is on sale for 20% off. There is 3% sales tax. We are asked to find the sales price before sales tax.
The sales price would be 80 minus 20% of 80.
![\text{Sales price}=80-(20)/(100)* 80](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mcon484ipjsux9vvn8ttqccy46g1xy7vz2.png)
![\text{Sales price}=80-(1600)/(100)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4qn1fv8zbrnspuyz26jj92ha5gow64pgt0.png)
![\text{Sales price}=80-16](https://img.qammunity.org/2020/formulas/mathematics/middle-school/n8okx9avcknjpeaidloml5srcbve6hu8hk.png)
![\text{Sales price}=64](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4yyj8nzavyhbfbqnptflljq53aoigy641g.png)
Therefore, the sales price before sales tax would be $64.
