1) Han got $2 from Clare, but still has less than $20:
x + 2 < 20
2) Mai spent $2 and has less than $20
x - 2 < 20
3) If Tyler had twice the amount of money he has, he would have less than $20
2x < 20
4) If Priya had half the money she has, she would have less than $20
1/2 x < 20
Explanations:1) Han got $2 from Clare, but still has less than $20
Let the original money Han had be x
When he got $2 from clare, his money became x + 2
Despite now having $(x + 2), he still has less than $20
The final inequality becomes:
x + 2 < 20
2) Mai spent $2 and has less than $20
Let the original money that Mai had be x
When he spent $2, his money became x - 2
Now, he has less than $20
The final inequality becomes:
x - 2 < 20
3) If Tyler had twice the amount of money he has, he would have less than $20
Let the amount of money Tyler has be x
If he had twice the amount he now has, his money would be 2x
Then he would have less than $20
The final inequality becomes:
2x < 20
4) If Priya had half the money she has, she would have less than $20
Let the amount of money Priya has be x
If she had half the amount she now has, her money would be 1/2 x
Then she would have less than $20
1/2 x < 20
