Final answer:
The final price of the bird feeder after a 7% discount and a 5% sales tax is applied would be $39.06.
Step-by-step explanation:
To calculate the final price of the bird feeder after the discount and sales tax, we first need to determine the discounted price. The discount is 7% of the original price of $40. To find this, we convert 7% to a decimal by dividing by 100, which gives us 0.07. Then we multiply the original price by this decimal.
$40 × 0.07 = $2.80
Subtract the discount from the original price to get the discounted price:
$40 - $2.80 = $37.20
Next, we calculate the sales tax which is 5%. Again, convert the percentage to a decimal (0.05) and multiply it by the discounted price:
$37.20 × 0.05 = $1.86
Finally, add the sales tax to the discounted price to find the final price:
$37.20 + $1.86 = $39.06
Therefore, the final price of the bird feeder after the 7% discount and 5% sales tax is $39.06.
