Question

Read the following problem. Write an inequality then solve it.
Sakura is going shopping for a t-shirt. What inequality shows the least amount of money (m) she should bring so she will still have $2.50 for subway fare after buying a t-shirt for $7.95? Graph the solution.

Answer 1

The inequality that shows the least amount of money Sakura should bring is:

m ≥ 7.95 + 2.50

To solve this inequality, we add $7.95 and $2.50:

m ≥ 10.45

Therefore, Sakura should bring at least $10.45 so she will still have $2.50 for subway fare after buying a t-shirt.

Graphing the solution would involve plotting all values of m that are greater than or equal to 10.45 on a number line.
