Anna has #300 and ojo has#1860,Anna saves #50 $ojo spends#70 a day,in how many days will they have equal amounts

300+50d =1860 -70d

120 d = 1560

day = 13

To find out how many days it will take for Anna and Ojo to have equal amounts, we need to calculate the difference between their initial amounts and how much they save or spend each day.

First, let's calculate Anna's savings per day. Anna saves #50 each day, so we can subtract this amount from her initial amount to get the remaining balance after each day:

Anna's balance after day 1: #300 - #50 = #250
Anna's balance after day 2: #250 - #50 = #200
Anna's balance after day 3: #200 - #50 = #150
...and so on.

Next, let's calculate Ojo's spending per day. Ojo spends #70 each day, so we can subtract this amount from his initial amount to get the remaining balance after each day:

Ojo's balance after day 1: #1860 - #70 = #1790
Ojo's balance after day 2: #1790 - #70 = #1720
Ojo's balance after day 3: #1720 - #70 = #1650
...and so on.

We will continue this process until Anna and Ojo have equal amounts. Let's calculate how many days it will take for their balances to be the same:

Day 1:
Anna's balance: #250
Ojo's balance: #1790

Day 2:
Anna's balance: #200
Ojo's balance: #1720

Day 3:
Anna's balance: #150
Ojo's balance: #1650

Day 4:
Anna's balance: #100
Ojo's balance: #1580

Day 5:
Anna's balance: #50
Ojo's balance: #1510

Day 6:
Anna's balance: #0
Ojo's balance: #1440

On the 6th day, Anna's balance becomes #0, and Ojo's balance is #1440. Therefore, it will take 6 days for Anna and Ojo to have equal amounts of money.
