b. $3 to place the call and $2 for each minute.
c. $5 to place the call and $3 for each minute.
d. $1 to place the call and $3 for each minute.

Answer 1

Lacey's plan costs $1 to place an international call and then $3 for each minute of the call. According to the details provided, the answer is option d. $1 to place the call and $3 for each minute.

Step-by-step explanation:

The student's question involves comparing the cost of making an international call using two different cell phone plans and identifying the correct cost structure of Lacey's plan. According to the information provided, Lacey pays $1 to place a call and $3 for each minute on her international calling plan. Therefore, if a call of a certain duration costs exactly the same under both Lacey's and Tamir's plans, we need to find which option describes Lacey's plan.

The correct answer is option d. $1 to place the call and $3 for each minute. This is directly stated in the question's premise. Therefore, no further calculations are necessary to determine the cost on Lacey's plan, as the question already reveals that Lacey's cost structure involves a $1 flat fee to place a call plus $3 per minute of call time.
