Answer:
a > -2
Step-by-step explanation:
-12a +7<31
Subtract 7 from each side
-12a +7-7<31-7
-12a <24
Divide by -12, remembering to flip the inequality
-12a/-12 >24/-12
a > -2
6,395.00 x 2 = 12,790
So $12,790 for the emerald rings.
5,314.00 x 2 = 10,628
So $10,628 for the pearl bracelets.
12,790 + 10,628 = 23,418
So $23,418.00 for all four pieces of jewelry.
