Answer:
0.3333 or 33.33%
Explanation:
The marginal propensity to consume is determined as the ratio between the monetary change in consumption to the change in income.
From $1050 to $1250, Jane increased her consumption by $200.
From $1700 to $2300, Jane's income increased by $600.
Her marginal propensity to consume is:
