One current school question and answer asked students to claim what they ponder is the main important challenge for a student to do in order for you to get success.

## Question:

Tavon has a gift card for \$55 that loses \$2 for each 30-day period it is not used. He has another gift card for \$45 that loses \$1.50 for each 30-day period it is not used. a. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal.
b. What will the value of each card be when they have equal value?

a. 20

b. \$15

Step-by-step explanation:

We can say that represent the 30-day period, then we can write the next equation:

Finding the , we find the number of 30-day periods until the value of the cards will be equal, then:

Then is needed a 20 30-day periods to have the cards with equal value.

Now to know the walue of each card we have:

Then each card will have a value of \$15

They could simply hopefully help the student answer the question by implementing the questions and answer examples. You could possibly then have a discussion with your classmate and continue the school learning by studying the problem to one another.
