Could you maybe provide us with a better explantion or picture?
The answer you have is good. You don't need to change anything.
Answer: 1,285, 1,282, 1,278
Step-by-step explanation:
For the first one it might be 26? i’m not so sure
20% off means you pay 80% of the price so you multiply by 0.8, and 7% tax means you multiply by 1.07
Resulting cost = 18.99*0.8*1.07 = 16.26
Hope this helps let me know if im wrong!
