Equations and Inequalities

You want to spend at most $1200 on a new laptop.  If you make a $400 down payment, then pay the same amount every month for 12 months.  Which Inequality could be use to solve to find out how much you can pay each month.

• 12x + 1200 > 400
• 12x + 400 < 1200
• 12x + 400 > 1200
• 12x + 400 < 1200

The booster club needs to raise at least $7,000 for new football uniforms. So far, they have raised $1,250. Write an inequality to find the average amounts each of the 92 members can raise to meet the club’s objective. 

• 1,250 + 92x > 7,000
• 1,250 + 92x ≥ 7,000
• 1,250 + 92x ≤ 7,000
• 1,250 + 92x < 7,000

Nick has $7.00. Bagels cost $0.75 each, and a small container of cream cheese costs $1.29. Write an inequality to find the numbers of bagels Nick can buy.

• 0.75b + 1.29 ≥ 7.00
• 0.75b + 1.29 ≤ 7.00
• 7.00b + 0.75 = 1.29
• 0.75 - 1.29 ≤ 7.00

Writing Inequalities
Ten times a number increased by four is no more than twenty-five.

• 10k - 4 < 25
• 10k + 4 > 25
• 10k + 4 = 25
• 10k + 4 ≤ 25

When is it necessary to reverse the direction of the inequality symbol?

• When multiplying or dividing on both sides of the inequality.
• When the coefficient of the variable is negative.
• When there are negative numbers in the problem.
• When multiplying or dividing both sides by a negative number.

Eleven more than two times a number is 17

• 11 + 17t = t
• 11t + 7t = 17
• 2t + 11 = 17
• 11 + 2 = 17

The space club is having some posters printed. The printer charges $250 plus $2 per poster. How can I figure out how many posters I could print for $1,000?

• 250x + 2 = 1000
• 1000 + 2x = 250
• 250 - 2x = 1000
• 2x + 250 = 1000
