Is there a correlation between the marginal utility and marginal rates

] consumption of Y is reduced by ∆Y
that leads to

But total utility remains unchanged, loss from -∆Y is offset by

Quantity of Y, consumed for some definite period

As total utility at B = total utility at A, than:

Switch from В to С:

Quantity of Y, consumed for some definite

Switch from С to D:

Quantity of Y, consumed for some definite

The more X is consumed, the less is its marginal utility
