what is the total utility at 4 units and the marginal utility when jack goes from consuming three pop tarts to four pop tarts?

Verizon [17]

The total utility of 4 units is 50 and the marginal utility is 5

Total utility is the sum of satisfaction that is derived from the consumption of units of a good or service.

Total utility can be determined by adding the marginal utility of each unit that is consumed.

Total utility of consuming 4 units = marginal utility of the first unit + marginal utility of the second unit + marginal utility of the third unit + marginal utility of the fourth unit

20 + 15 + 10 + 5 = 50

Marginal utility is the change in total utility when consumption increases by unit. Marginal utility is 5

Shawn wants to model the number 13,450 using base-ten blocks. how many large cubes, flats, and longs does he need to model the n

enot [183]

1 rod or long is a column of 10 unit cubes.

10 longs placed side by side, form a flat (with dimensions 10×10)

10 flats, placed on top of each other form a large cube, with dimensions 10×10×10 = 1000 cubes.
-------------------------------------------------------------------------------------------------

each small cube (unit cube) represents the number 1.

thus each long represents 10
each flat represents 100

and each large cube represents 1,000

The number 13,450 can be written as

1*10,000+3*1000+4*100+5*10 using the expanded form.

This means that there are 13 large cubes, 4 flats and 5 longs needed to model the number.

Answer: 13 large cubes, 4 flats, 5 longs
