Question 86133
I am so lost doing inequalities. Could someone explain how you would write this?

You have at least $30 in change in your drawer, consisting of dimes and quarters. Write an inequality that shows the different number of coins in your drawer.
LET NUMBER OF DIMES BE = D..........ITS VALUE =10D CENTS
LET NUMBER OF QUARTERS = Q............ITS VALUE =25D CENTS
TOTAL VALUE =10D+25Q CENTS
THIS IS AT LEAST 30$=3000 CENTS
10D+25Q>=3000
2D+5Q>=600
