Answer:
3 dress shirts and 3 T-shirts
4 dress shirts and 1 T-shirt
Step-by-step explanation:
You must spend at least $93 and no more than $100.
2 dress shirts: $42 + 5 T-shirts: $60 = $102 too much money
2 dress shirts: $42 + 4 T-shirts: $48 = $90 too much money left
3 dress shirts: $63 + 3 T-shirts: $36 = $99 this works
4 dress shirts: $84 + 1 T-shirt: $12 = $96 this works
5 dress shirts: $105 too much money
Answer:
3 dress shirts and 3 T-shirts
4 dress shirts and 1 T-shirt

Choice B and Choice C
====================================================
Reasoning:
c = cost of one crate (some unknown amount in dollars)
c+20 = cost of a crate and a leash
5(c+20) = cost of five sets of items mentioned
5(c+20) = 475 is one equation we can form
5c+100 = 475 is another equation we can form
I used the distributive rule to go from 5(c+20) to 5c+100.
The 100 indicates that the five leashes combine to $100, since 5*20 = 100.
The 5c represents the cost of all five crates combined.
So 5c+100 is another way to express the total cost of all five crates and all five leashes.
---------------
Side note: Solving either equation leads to c = 75, meaning that each crate costs $75.
Answer:
x=16 x=2
Step-by-step explanation:
x^2-18x+81=49
x^2-18x+81-49=0
x^2-18x+32=0
(x-16)(x-2)=0
x-16=0
+16+16
x=16
x-2=0
+2 +2
x=2
