Answer:
1080.
Step-by-step explanation:
0.00025 tonnes = 0.00025 * 1000 = 0.25 kg.
Total number of packets
(3 *90) / 0.25
= 12*90
= 1080.
First, determine what is 40% of $600. Multiple 40 (as a decimal) by 600.
0.4 x 600 = 240
Therefore, the discount is $240 off $600.
Subtract the two values to find price (before tax): 600 - 240 = 360
So the TV will cost $360 before tax.
The tax is 8.5%. Multiply 8.5 as a decimal by 360 to find the amount of tax added.
0.085 x 360 = 30.6
Add 30.6 and the price before tax to find the final price.
30.6 + 360 = 390.60
Therefore, the final price of the TV is $390.60
