Even # --------- if it ends with 0, # of ways = 6*5*4 = 120 if not, 3 ways for ending digit, 5 ways for 1st digit, 5*4 for middle digits = 300
so total ways = 420
odd # --------- 4 ways of ending digit, 5 ways for 1st digit, 5*4 for middle digits = 400 ways
< 4000: ---------- 3 ways for starting digit, 6*5*4 ways for remaining digits = 360 ways
> 3000 & < 4000 ------------------------ 1 way for starting digit , 6*5*4 for remaining digits = 120 ways
Answer:
total = $41
Step-by-step explanation:
If Julio spent $41 and now has no money that means that after spending that money he was left with $0. Having both of these numbers we can make a very simple algebraic equation to find out his total before the purchase.
total - $41 = $0
Now we simply add $41 to both sides which will give us the actual amount of the total.
total - $41 = $0
+$41 +$40
-----------------------------
total = $41
Now we can see that Julio had a grand total of $41 before making his purchases.
