Money Algebra 1A

If x represents the amount of money you have and you spend $5, what is the algebraic expression for the amount of money you have left?

• x * 5

• 5 - x

• x - 5

• x + 5

Solve for x: 3x + 10 = 25

• x = 15

• x = 20

• x = 10

• x = 5

If you have $20 and you earn $5 each day, write an algebraic expression to represent the total amount of money you will have after d days.

• 20 / 5d

• 20 + 5d

• 20 * 5d

• 20 - 5d

Simplify the expression: 2x + 3y - 4x + 5y

• 6x + 8y

• 2x - 8y

• -2x + 8y

• -2x - 8y

If you have $50 and you spend x dollars, write an algebraic expression to represent the amount of money you have left.

• 50x

• $50 - x

• x - 50

• 50 + x

Solve for x: 2(x + 3) = 16

• x = 12

• x = 8

• x = 5

• x = 10

If you have $100 and you save $20 each week, write an algebraic expression to represent the total amount of money you will have after w weeks.

• 100 + 20w

• 100 / 20w

• 100 * 20w

• 100 - 20w

Simplify the expression: 4a - 2b + 3a + 5b

• 5a - 2b + 3a + 5b

• 2a + 3b

• 7a + 3b

• 6a + 7b

If you have $80 and you spend half of it, write an algebraic expression to represent the amount of money you have left.

• 80-2

• 2/80

• 80*2

• 80/2

Solve for x: 5x - 8 = 12

• x = 10

• x = 6

• x = 2

• x = 4
