First you have make the 2 and a half into 5/2. Then you have to find a common denominator of the two fractions, which would be 8. So the 7/8 you dont need to do anything to but the 5/2 you do... so multiply both the top and the bottom by 4 so you can get 8 on the bottom. that would be 20/8. now you can add them. so 7/8 + 20/8 = 27/8

Answer: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

Comment
The f(x) notation means that were ever you see n x on the right you put the value of x.
The question is which point has x = - 3 and what is the associated y value?
You could do it this way, just so you understand it.
