Answer:
The total cost of a bicycle after the tax = $900.8
Step-by-step explanation:
Given
- The cost of a bicycle before tax = 837.95 (let say in $)
To determine
The total cost of the bicycle with a sales tax include
The tax amount can be calculated by multiplying Sales tax i.e. 0.075 with the cost of bicycle before tax i.e. 837.95.
Thus,
Tax amount = 7.5% × 837.95
= 0.075 × 837.95
= $62.85
Thus, the tax amount is: $62.85
Total cost after the tax can be calculated by adding the Tax amount and the cost before tax.
Therefore,
The total cost of a bicycle after the tax = $62.85 + $837.95
= $900.8
Hence, the total cost of a bicycle after the tax = $900.8
____________________________False
a = 30
a = 16
-a² + 46a -480 = 0
(-a + 30) (a -16) = 0
(-a)(a) + (-a)(-16) + 30(a) + 30(-16) = 0
-a² + 16a + 30a -480 = 0
-a² + 46a - 480 = 0
(-a + 30) = 0 ; (a - 16) = 0
-a = -30 ; a = 16
a = 30
To check:
a = 30
-(30)² + 46(30) - 480 = 0
-900 + 1380 - 480 = 0
480 - 480 = 0
0 = 0
a = 16
-(16)² + 46(16) - 480 = 0
-256 + 736 - 480 = 0
480 - 480 = 0
0 = 0
