Answered by Ms. Sue
(5 * 12) + 30d < 150

Answered by Natoutou
what does < mean? Ms.Sue?
Answered by Ms. Sue
< means less than.

Solve this the same way you'd solve an equation with an equal sign.
Answered by Natoutou
Ms.Sue so its 30d-150?
Answered by Ms. Sue
No.

(5 * 12) + 30d < 150

60 + 30d < 150

Subtract 60 from both sides.




Answered by Natoutou
I don't quite understand when u say subtract 60 from both sides can you please explain
Answered by Ms. Sue
You need to isolate the variable. Also, remember that subtraction is the opposite of addition.

You're welcome, Natoutou.
Answered by Patrick Kimani
If Jane buys 5 T-shirts, she can buy at most 3 dresses or not more than 3 dresses.

12x + 30y ≤ 150

12*5 + 30y ≤ 150

60 + 30y ≤ 150

30y ≤ 150 - 60

30y ≤ 90

y ≤ 90/30

y ≤ 3

I hope that helps, Folks!
