Answer:
The total amount = $175
Step-by-step explanation:
Let the total amount in his bank account = x
Nick decided to take 2/5 of the money in his bank account and donate it to a local charity
So, he donates with [tex]\frac{2}{5} x[/tex]
If nick donated $70 to a local charity
so, [tex]\frac{2}{5} x = 70[/tex]
solve for x
∴ x = 5*70/2 = 350/2 = $175
So, The total amount = $175
