10 points! 10: gavin builds furniture for a living. he sells chairs for $45 and tables for $70 each. it takes gavin 4 hours and $10 worth of supplies to build each chair. a table requires 10 hours and $15 worth of supplies to make. gavin wants to work for no more than 40 hours per week and spend no more than $80 on materials. write a system of inequalities and state 3 possible combos.

Let's assume

number of chairs =x

number of tables =y

we are given

Gavin builds furniture for a living. he Sells chairs for $45 and tables for $70 each

So, we can find objective function as

now, we can find inequalities

A table requires 10 hours and $15 worth of supplies to make

so, total hours to make table =10y

amount spent on table =15y

It takes Gavin 4 hours and $10 worth of supplies to build each chair

so, total hours to make chair =4x

amount spent on chair =10x

total number of hours to make chair and table =4x+10y

Gavin wants to work for no more than 40 hours per week

so, we get

spend no more than $80 on materials

so, we get

so,

objective function:

Constraints:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

the correct answer is $7.38
