Ok, so first you solve whatever is in the parentheses.
(28 • 5-5 • 190)-2•228
28• 5 = 140
Then 5 •190 = 950
Then multiply 950 • 140 = 133,000
Then it should look like this:
133,000-2•228
Multiply 2 • 228 = 456
Then subtract 456 from 133,000.
The answer should come out to 132,544.
Each piece in the 5 pack cost: .17
Each piece in the 8 pack cost: .15
So the answer would be 2 cents cheaper
1. 2+4=6
2. 2X7=14
3. 4X3=12
4. 7X3=21
5. 12+14=26
6. Simplify 26/21
7. 26-21= 5 so it simplifies to 1 5/21
8. 6+1 5/21=6 5/21
Answer:
Advantage: Cash-back cards are more flexible and you can use the money you earn to pay for travel, merchandise, or help pay off your balance.
Disadvantage: You have less of a record of where you spend your money, cash can be lost or stolen, and when it happens you have less recourse than if you had lost a credit card.
