4 Problems that I need not only the answers to,but guidance as to how to solve

all,

Here they are I just have no clue if I'm being honest and I need to know answers and HOW!!!

From the following equation, find the values of income Y and consumption spending C, when:

From the following equation, find the values of income Y and consumption spending C, when:

Y = C + I + G | Income |

C = 18 + 0.8Y | Consumption expenditure |

I = 12 | Investment expenditure |

G = 10 | Government expenditure |

Y = | Equilibrium level of income **<-----32 is showing up for some reason but shouldn't be** |

Given the level of income Y, what is the level of consumption expenditure?

C =

A firm buys two inputs, labor L and capital K, the total amount of which cannot exceed 100. The wage is $8, and the rental rate is $10. The firm can at most spend $840 on the two inputs.

This data can be summarized in the following equations:

Input limit: K + L = 100

Budget limit: 8L + 10K = 840

What are the quantities of two inputs the firm must buy in order to produce a maximum output, given input and budget constraints?

L= **<---NOT RIGHT**

K= **<---NOT RIGHT**

The demand for coffee is given by the following equation, where *Q*^{D} stands for the quantity demanded and *P stands for price.*

*Q*^{D} = 100 - 4*P*

The supply of coffee is given by the following equation, where *Q*^{S} stands for the quantity supplied and *P stands for price.*

*Q*^{S} = 10 + 2*P*

**a. What is the slope of demand? Slope = **

**b. At what price is quantity demanded equal to zero? ***P = *

**c. What is the slope of supply?**

Slope =

**d. At what price is quantity supplied equal to zero?**

*P = *

**e. In the diagram below use the line tool to plot the demand and supply curves using the original equations and your values for the intercepts and slopes of each equation.**

**Instructions: Select the tool "Demand" to plot the demand curve such that the endpoints touch each axis (where P = 0 and Q = 0). Select the tool "Supply" to plot the supply curve using the vertical intercept for one endpoint and the other point located at a value of Q = 100.**
