Answer:
12 gifts
Step-by-step explanation:
set the equation to 270-15x=330-20x
david: 12g=270
her: 20g=330
david buys 5 gifts he will have 210 dollars left in his account ( 12x5= 60 & 270 - 60 = 210)
if kristin buys 6 gifts she will have 210 dollars left ( 20x6= 120 & 330-120= 210)
We know that,
Accordingly,
I thinks it's point 2 and if it's wrong I am sorry for that
9 lb 3 oz
(3 + 5) lb + (9 + 10) oz
8 lb + 19 oz
16 oz = 1 lb
(8 + 1) lb + (19 - 16) ox
