Answer 1

He spent

Fraction: 3/10

Weights: $ 210

He stayed

Fraction: 7/10

Weights: $ 490

Step-by-step explanation:

On the excursion Cristian spent 3/10 of what he had, therefore he still has:

1 - 3/10 = 7/10

Now, that 7/10 represents $ 490, to calculate what value 3/10 has, it would be:

(3/10) * 490 / (7/10) = $ 210

In total he had: 210 + 490 = $700
