we need to multiply : 1/5*3/4 multiply 1 by 3 on the tops so we have 3/5*4 5*4=3/20
For the first part:Every shirt she grabs, will cost her dollars, so if she grabs 3 shirts, then the cost of the shirts is:

With the same rationale, if she grabs 2 pairs of jeans, the cost of the jeans is:

So, her total is:

If you subtract 3 from the total, then the expression is:
For the second part:If she's paying 3 less for each shirt, then the cost of 3 shirts will become:

In the same fashion, for the two jeans:

So the expression for the total cost is:
For number three:The amounts are different because the cost of the total purchase is different than the cost of each element that makes up the total purchase.
For number four:If you're the owner, you want to give the smallest amount of discount (the one in part 1/a).
So you could clarify by saying there's 3 dollars of the TOTAL purchase's cost.
Answer:
If the question is how many student enroll in the school each year then the answer is 1080
Step-by-step explanation:
<DFA = 180 -(66+56) = 58
<EOB = 360- (90+90+58) = 122
<COB = 360 - (90+90+66) = 114
<COE = 360 - (90+90+56) = 124 so arcCE = 124
answer
<DFA = 58
<EOB = 122
<COB = 114
arc CE = 124
