To find the product of 4*80:
Remove the 0 from 80 (4*8)
Multiply as you would (or just add 8+8 4 times)
When you get your answer (32), add the 0.
Answer: 320
Answer:
Cost of each hat: $5
Cost of each mask: $3
Step-by-step explanation:
Let be "x" the cost in dollars of a party hat and "y" the cost in dollars of a mask.
Set up a System of equations using the information given in the exercise:

You can use the Elimination Method to solve this System of equations:
1. You can multiply the first equation by -1.
2. Then you must add the equations.
3. Solve for "y".
Then:

4. Now you can substitute the value of "y" into any original equation.
5. Finally, solve for "x" in order to find its value.
Then:

<span>10% of 8350=$835.
15% of 25600(8350 from 33950) =25,600 15% of 25600= 3840.
25% of 3500. (32450 minus 33950= 3500 25% of 3500 =875.
Add the three and you get $5550. Of course you could have eliminated step two and three by anticipating a tax that far exceeded the other choices which were way to low to even consider.
Work this out for yourself. It is simple and fun when you get the hang of it.
