Matt's ordinary demand function for commodity x1(p1, p2, i)=(3i)/p1. how will a 1% increase in p1 affect matt's expenditures on x1 (use our approximization formula here)?

(a) his expenditure on x1 will increase by 1%
(b) his expenditures on x1 will not change.
(c) his expenditures on x1 will decrease by 1%.
(d) it is not possible to determine how matt's expenditures will change from the information given.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

understand that i don't know the answers

will someone answer his question

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
