Considering the discount and the sales tax, the equation that represents the situation is:
[tex]C(x) = 0.6955x[/tex]
-------------------------------
- The original price, without discount, is of x.
- Promotional sale for 35% off all items, which means that the amount paid is 100% - 35% = 65% of the original price, thus x is multiplied by 0.65.
- 7% sales tax means that x is also multiplied by 100% + 7% = 107% = 1.07.
Thus, the equation that represents the cost is:
[tex]C(x) = x \times 0.65 \times 1.07 = 0.6955x[/tex]
