9 white ribbons were awarded
Step-by-step explanation:
make white x
make blue b and make red r
b=x-1
r=x+3
w=x
add them up
x-1+x+3+x=29
x-1 +x+3 is 2x+2
2x+2+x=29
3x+2=29
subtract 2 on both sides
3x=27
divide by 2
x=9

Answer:
5
Step-by-step explanation:
Oranges: 3.46 $
Grapes: 1.36 $
Apple: They didn't leave you with the cost of the apple so I don't know
Add 3.46 plus 1.36 and you get 4.82. Then round that to 5.00.
20% off means it is selling for 80% of the original price ( 100% - 20% =80%)
Divide the sale price by 80% as a decimal:
380/0.80 = 475
The original price was $475
Justify:
Multiply the original price by 20% and subtract:
475 x 0.20 = 95
475-95 = $380 which is the sale price.
