The equation is 3n - 5 1/2. 5 1/2 = 5.5
3n - 5.5
n could equal 1 so, 3 x 1 - 5.5 = -2.5
3n - 5 1/2 = -2.5

Answer:
Anna and Ojo will have same amount after 13 days.
Step-by-step explanation:
Given that:
Anna has 300 naira
She saves 50 naira per day.
Let,
x be the number of days.
y be the amount saved
y = 50x + 300
Ojo has 1860 naira
He spends 70 naira per day.
Let,
x be the number of days
y be the amount left
y = 1860 - 70x
For equal amount, the equations will be equal
50x +300 = 1860 - 70x
50x + 70x = 1860 - 300
120x = 1560
Dividing both sides by 120

Hence,
Anna and Ojo will have same amount after 13 days.
