Write an equation that can be used to determine c, the amount of candy each club must sell so that the total amount of money raised is the same.

Two after-school clubs are raising money.

● The math club has already raised $500 and is selling candy for $2 each. ● The drama club has already raised $350 and is selling candy for $3 each.

• 500 + 2c = 350 + 3c

• 500 + 3c = 350 + 2c

• 500c = 350c

• 2c + 3c = 500 + 350

Daria and Alicia are reading the same book for class. Daria has completed reading 100 pages of the book and plans to read an additional 5 pages every night until the book is finished. Alicia has completed reading 75 pages of the book and plans to read 10 pages per night until the book is finished. Write an inequality that could be used to determine the number of pages Alicia must read to have more of the book completed than Daria.

• 75 + 10x > 100 + 5x

• 100 + 5x > 75 + 10x

• 75 + 5x > 100 + 10x

• 100 + 10x > 75 + 5x
