Question

A box of crayons costs $1.75, including tax. Mr. Valentino wants to purchase boxes of crayons for his class and has a $25 budget. Write an inequality to solve for the number of boxes of crayons Mr. Valentino can purchase with his budget.

$1.75x ≤ $25
$1.75x ≥ $25
$25x ≤ $1.75
$25x ≥ $1.75





A cab charges $1.50 for the flat fee and $0.50 for each mile. Write and solve an inequality to determine how many miles Sharon can travel if she has $25 to spend.

$0.50 + $1.50x ≤ $25; x ≤ 16 miles
$0.50 + $1.50x ≥ $25; x ≥ 16 miles
$1.50 + $0.50x ≤ $25; x ≤ 47 miles
$1.50 + $0.50x ≥ $25; x ≥ 47miles


i will give a medal if someone can help me

Answer 1

The 1st answer on question 1 because it has to be less than $25 and the 3rd answer on question 2 because it's 1.50 for a flat fee and 0.50 cents a mile and you don't know how many miles Sharon is going to go but it has to be under or equal to 47 miles because other wise, it would be over her budget of $25.

Answer 2

Solve for x: 4 − (x + 2) < −3(x + 4)

x < −7
x > −7
x < −9
x > −9

Malcolm has $638.54 in his checking account. He must maintain a $500 balance to avoid a fee. He wrote a check for $159.50 today. Write and solve an inequality to solve for the least amount of money he needs to deposit to avoid a fee.

638.54 + 159.50 − x ≥ 500; x ≥ $298.04
638.54 + 159.50 − x ≤ 500; x ≤ $298.04
638.54 − 159.50 + x ≥ 500; x ≥ $20.96
638.54 − 159.50 + x ≤ 500; x ≤ $20.96
