Answer:
<u>6</u><u>c</u><u>²</u> + <u>2c</u> + <u>1</u>
Step-by-step explanation:
- 4 + 4c + 3c² - 2c + 3c² - 3
Rearrange the experresion.
- 4 - 3 + 4c - 2c + 3c² + 3c²
Combine like terms.
Use the commutative property to reorder the terms.
- <u>6</u><u>c</u><u>²</u> + <u>2</u><u>c</u><u> </u> + <u>1</u>
The cost of the meal would be $18.25. You can find this answer by multiplying 7.30 by 2.5, since the decimal form of 250% is 2.5.
