1) brown braid : 4*2.40 = $16.80
black lace : 7*2.40 = $29.40
gold ribbon : 13*2.40 = $31.20
2) 4 + 7 + 13 = 24 yards <
3) 16.80 + 29.40 + 31.20 = $77.40 <

Answer:
17%
Step-by-step explanation:
to find the percentage of something, you have to fill out the following formula:
x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:
125x = 2125
then you have to divide, to single out x:
the answer is 17
so it is 17%
