Answer:
49.5 meters of linen were left after the sale.
Step-by-step explanation:
Given that there are 100 meters of linen
And 15.75, 22.50 and 12.25 meters are sold.
This means that the sold linen has to be added to find the total linen sold.
And then the quantity of sold linen will be subtracted from 100 to find the meters of linen left.

Left linen will be:

Hence,
49.5 meters of linen were left after the sale.
18-4.25=13.75 the original minus what she already spent
13.75-9.75=4 that minus what she has to save
.50x=4 where x=the number of packages
divide both sides by .50
x=8 Fiona can buy 8 packages of crackers
Hope that helps.
Answer:
28
Step-by-step explanation:
Mikhail's age:x
Gabrielle's age:2x
x+2x=84
3x=84
x=84÷3
x=28
You simply multiply the two and distribute to solve. I am starting with t(x) because I think it is easier.
(x+4)*(2x^2+3x-4)
2x^3+3x^2-4x+8x^2+12x-16 (distribute)
2x^3+11x^2+8x-16 (combine like terms)
