## anonymous 3 years ago Isadora bought 4 trees to plant in her backyard and spent no less than eighty-four dollars altogether. How many dollars could each tree have cost? Let t represent how many dollars each tree cost. t is greater than eighty t is greater than or equal to eighty t is greater than twenty-one t is greater than or equal to twenty-one

4 divide 4 is 1

2. anonymous

8 divided by 4?

3. nincompoop

$4t \ge 84$

4. anonymous

t is greater than or equal to eighty

5. nincompoop

the question is: how much could EACH tree cost? meaning you will have to divide 4t by 4 and also 84 by 4 this gives you: $\frac{ 4t }{ 4 } \ge \frac{ 84 }{ 4 }$

84 divided by 4 = 21

9. nincompoop

no...

10. nincompoop

4/4 is 1 but you have t

11. anonymous

t = 21

12. anonymous

t > 21

13. nincompoop

NOT EQUAL. we are using inequality greater than or equal to, because in the original problem it says: spent no less than 84 dollars...

14. anonymous

$t \ge 21$
