1. check the pic at the bottom.
2. Since we are asked for percentage, so a ratio, let the number of kids with both umbrellas and raincoats be 8.
Let x be the number of children with raincoats, but not umbrellas
Let y be the number of children with umbrellas but not raincoats.
3. Then, x+y+8=100 (100% is 100, since we assumed 8% to be 8 kids)
this gives us x+y=92.
4. "The total number of kids with umbrellas is twice the total number of kids with raincoats. " :
8+y=2(x+8)
8+y=2x+16
y-2x=8
5. substitute x=92-y in y-2x=8, we get
y-2(92-y)=8
y-184+2y=8
3y=192
y=64
64% ofkids bring only an umbrella.
Answer:
The sale amount of the pair of shoes will be: $27
Step-by-step explanation:
The original price = $29.99
Mark down = 10%
Mark down amount = 10% × 29.99
= 0.1 × 29.99
= $2.99
Thus, the sale price = Original price - Mark down amount
= $29.99 - $2.99
= $27
Therefore, the sale amount of the pair of shoes will be: $27

Answer:
60.
Step-by-step explanation:
I can't see the question above this and what information it gives, but If I'm not mistaken, that shape is a rectangle, so regardless of whether there's a piece of the last side missing, the sides across from each other are congruent in size.
So if the top is 14, then the bottom is 14, and since the left side is 16, then the side missing a piece adds up to 16.
(14*2) + (16*2) =
28 + 32 = 60.
