(a)
Write and solve an inequality that shows how much money she can spend that month after buying a concert ticket.
(a)
Answer to Problem 5MCQ
Lupe can spend that month after buying a concert ticket no more than $15.
Explanation of Solution
Given:
Lupe`s allowance for the month is $60. She wants to go to a concert for which a ticket costs $45.
Concept Used:
Let m represents how much money she can spend that month after buying a concert ticket.
The inequality:
Calculation:
The inequality:
Solve for m:
Lupe can spend that month after buying a concert ticket no more than $15.
Thus, Lupe can spend that month after buying a concert ticket no more than $15.
(b)
Write and solve an inequality that shows how much she can spend both these purchases and the concert ticket.
(b)
Answer to Problem 5MCQ
Lupe can spend no more than $3.01for both these purchases and the concert ticket.
Explanation of Solution
Given:
Lupe`s allowance for the month is $60. She wants to go to a concert for which a ticket costs $45.
She spends $9.99 on music downloads and $2 on lunch in the cafeteria. Write and solve an inequality that shows how much she can spend either these purchases or the concert ticket.
Concept Used:
Let m represents how much money she can spend both these purchases and the concert ticket.
The inequality:
Calculation:
The inequality:
Solve for m:
Thus, Lupe can spend no more than $3.01for both these purchases and the concert ticket.

Explanation of Solution
Given:
Lupe`s allowance for the month is $60. She wants to go to a concert for which a ticket costs $45.
She spends $9.99 on music downloads and $2 on lunch in the cafeteria. Write and solve an inequality that shows how much she can spend either these purchases or the concert ticket.
Concept Used:
Step 1: make the inequality equation.
Step 2 : Subtract the numbers to both sides.
Step 3: Simplify.
Follow all the rules for solving the inequality.
