Answer:
Let's denote:
Number or gifts cost 20 = x
Number or gifts cost 22.5 = y
Then, we have:
x + y = 10
20x + 22.5y = 217.5
=> 20(10 - y) + 22.5y = 217.5
=> 2.5y = 17.5
=> y = 7 (Number or gifts cost 22.5)
=> x = 10 - 7 = 3 (Number or gifts cost 20)
Hope this helps!

Answer:
52 inches by 29 inches
Step-by-step explanation:
Let one side by 16x and the other side be 9x
We know the diameter is 60 inches
Using the Pythagorean theorem
a^2 + b^2 = c^2
(16x) ^2 + ( 9x) ^2 = 60 ^2
256 x^2 + 81x^2 = 3600
Combine like terms
337 x^2 = 3600
Divide each side by 337
337x^2 /337 = 3600/337
x^2 =10.68249258
Take the square root of each side
sqrt(x^2) =sqrt(10.68249258)
x =3.268408264
The sides are 16x by 9x
16*(3.268408264) =52.29453223 or 52
9 *(3.268408264)= 29.41567438 or 29
They would need 38 pounds of grapes for 16 cartons of raisins
