Ashopper purchased 8 t shirts and 5 pairs of pants for 220. the next day he purchased 5 t shirts and 1 pair of pants. how much does a t shirt and each pair of pants cost

the price for one shirt is $20

the price for one pair of pants is $12

Step-by-step explanation:

The question is incomplete. The complete question is

A shopper purchased 8 t shirts and 5 pairs of pants for $220. The next day he purchased 5 t shirts and 1 pair of pants for $112. How much does a t shirt and each pair of pants cost.

The solution is

Let x represent the price for one t shirt.

Let y represent the price for one pair of pants.

A shopper purchased 8 t shirts and 5 pairs of pants for $220. This means that

8x + 5y = 220 - - - - - - - - - -1

The next day he purchased 5 t shirts and 1 pair of pants for $112. This means that

5x + y = 112 - - - - - - - - - - - 2

Multiplying equation 1 by 5 and equation 2 by 8, it becomes

40x + 25y = 1100

40x + 8y = 896

Subtracting, it becomes

17y = 204

y = 204/ 17 = 12

Substituting y = 12 into equation 2, it becomes

5x + 12 = 112

5x = 112 - 12 = 100

x = 100/5 = 20

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.
