Coach Wilson ordered T-shirts for the basketball team from two different T-shirt suppliers. One supplier charged $16 for each shirt, as well as 5% for shipping. The other supplier charged $18 for each shirt, plus 7% for shipping.Part A
Coach Wilson ordered the same number of shirts from each supplier. Write an equation to find the shipping charges he paid to each supplier.
Part B
The first supplier gave Coach Wilson a discount of 10% off of his order total. The second supplier gave him a discount of $20 off of his order total. Write an equation to find the total cost, T, of the shirts.
Part C
Coach Wilson ordered 15 T-shirts from each supplier. How much did he pay?
Answers
Answer 1
Answer:
Part A: # of shirts bought in total (T)times cost of each shirt (E) =X. X times .5 (same as 5%)= shipping charge (S) = first: T*E=X. second: X*.5=S
Part B: vendor 1: # of shirts bought (A) times cost of each shirt (B) plus shipping charge(C) times 10%=T. A*B+C*.10=T
vendor 2: # of shirts bought (A) times cost of each shirt (B) plus shipping charge (C) minus $20= T. A*B+C-20=T
Part C:
vendor 1: 15*16=240 (total # of shirts * cost of ea.) 240+8= 248 (1st answer + $8 of shipping) 248*.10= 24.80 (2nd answer * 10% discount) 248-24.80= [223.20] (2nd answer - 10%) vendor 1 total cost: 223.20.
vendor 2: 15*18=270 (# of shirt bought * cost of ea.) 270+12.60=280.60 (answr 1 + shipping cost) 280.60-20=[260.60](answr 2 -$20discount) vendor 2 total cost: 260.60.
1. We assume, that the number 12 is 100% - because it's the output value of the task. 2. We assume, that x is the value we are looking for. 3. If 100% equals 12, so we can write it down as 100%=12. 4. We know, that x% equals 36 of the output value, so we can write it down as x%=36. 5. Now we have two simple equations: 1) 100%=12 2) x%=36 where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that: 100%/x%=12/36 6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 36 is what percent of 12
100%/x%=12/36 (100/x)*x=(12/36)*x - we multiply both sides of the equation by x 100=0.333333333333*x - we divide both sides of the equation by (0.333333333333) to get x 100/0.333333333333=x 300=x x=300
now we have: 36 is 300% of 12
Why does it take 3 copies of 1/6 to show the same amount as 1 copy of 1/2?
Answers
3*1/6= 3/6 for three copies. 1/2 can equal half of any number. 3 is half of 6, so 3/6=1/2. 1/2 d 3/6 are equivalent fractions.
I hope this helped you!
How is subtracting like fractions similar to adding like fractions
Answers
Because they both have the same rule. They have to have the same denominator.
Well,
Adding and subtracting like fractions are similar in that both cases simply require you to add the numerators. This is opposed to adding and subtracting non-like fractions because you have to convert them into like fractions.

If $2887.51 is 60%, What is 100%?
Answers
4812.52. I got this answer by seeing what number do you multiply 60 to get 2887.51. Then I multiplied that number by 100.
