1) A cab charges $1.75 for the first mile and $0.25 for each additional mile.
Write and solve an inequality to determine how many miles Eddie can travel if he has $15 to spend.

A) $1.75 + $0.25x ≤ $15; x ≤ 53 miles

B) $1.75 + $0.25x ≥ $15; x ≥ 53 miles

C) $0.25 + $1.75x ≤ $15; x ≤ 8 miles

D) $0.25 + $1.75x ≥ $15; x ≥ 8 miles

The total cost is equal to the sum of the cost for first mile and that of the x number of miles after that. This sum should not exceed Eddie's available amount. The equation that best represent the condition is,
                                      $1.75 + $0.25x ≤ 15
The value of x is x ≤ 53 miles. Therefore the answer is letter B.

2. Let x be the number of crayons that Mr. Valentino can buy, the inequality that best represent the situation is,
                                         1.75x ≤ 25
The value of x is approximately 14.29 but Mr. Valentino can only buy 14 crayons.
