Answer:
0.31
Explanation:
Income elasticity of demand measures the responsiveness of quantity demanded to changes in income
Income elasticity of demand = percentage change in quantity demanded / percentage change in income
Percentage change in income = = 2.3
when income was $300, ramen was demanded twice, that is 2/7 times a week. converting to fraction gives 0.29
Percentage change in quantity = = 0.72
0.72/2.3 = 0.31
Answer: $186,000
Explanation:
January is the 2nd month from November which means that all of November's $31,000 will be collected in January.
January is the first month after December so 30% of December sales should be collected in January. 50% has already been collected in December and this left $50,000.
Total credit sales in December must have been:
= 50,000 / 50%
= $100,000
Amount to be collected in January for December:
= 100,000 * 30%
= $30,000
Amount to be collected from January credit sales:
= 50% * 150,000
= $75,000
January cash sales = $50,000
Total cash in January :
= 31,000 + 30,000 + 75,000 + 50,000
= $186,000
