2. Use the scenario to solve the following inequalities.
a. Write an inequality to express the number of smartphones in the
company’s inventory (
i
).
b. Write an inequality to express the number of smartphones sold (s).
c. Is the following statement true? Explain why or why not.
s < 4,000,000 > i
d. Customers who have already purchased their new smartphones can
expect to receive their smartphones in less than three weeks. Write
an inequality that expresses the number of days a customer could
expect to wait. Explain what your answer means.
Last week, the newest smartphone was released for pre-order
before it will be available in retail stores. The smart phone
was so popular that the company announced it set a new
record number of first day pre-orders. More than four million
new smart phones were pre-ordered within the first 24 hours.
That was so many, the pre-orders for the phone exceeded the
company’s inventory. More are on the way, but many
customers will have to wait less than three weeks for their
new smart phones to arrive.
