ANNA HAS 300 AND OJO HAS 1860 IF ANNA SAVES 50 A DAY AND OJO SPENDS 70 A DAY AFTER HOW MANY DAYS WILL THEY HAVE EQUAL AMOUNTS?
number of days this will happen ---- x
300 + 50x = 1860 - 70x
solve for x
Let me know what you get so I can check it.
after x days, their money will be equal if
300+50x = 1860-70x
309+50x=1860-70x
Collect like terms
300-1860=-70x-50x
-1560= -120x
X=-1560÷ -120
X=13
Excellent work
