First, calculate the area of the rectangular yard.
A = L x W where A equals area, L equals length, and W equals width.
According to your stated problem:
A = 31 x 49
A = 1519 square feet <-------Area of Rectangular yard.
Answer:
Yes and she would have $2 left over because all the food costs $91.
Step-by-step explanation:
We should set up an equation so that everything makes sense. A calculator would be wise for this problem, but I am going to lay it out anyhow.
We should convert the mixed numbers to improper fractions to not be confused. 3 1/2 becomes 7/2 or 3.5 and 2 1/3 becomes 7/3.
From your wording, we can assume that the money Mrs. Donnelly has is either greater than or equal to $93.
Thus, we have 12*(7/3) + 18*(7/3) is equal to or greater than 93 (this is an inequality).
The math shows that the food costed 91 and so she only has $2 left.

Answer: She should buy 21 gallons of fruit juice and 7 gallons of soda.
Step-by-step explanation:
Let x be the number of gallons of fruit juice and y be the number of gallons of soda.
Then,
Multiply 3 on the both sides of equation (1), we gte
Using elimination method, subtract (3) from (2), we get
Substitute y=7 in (1), we get 
Hence, She should buy 21 gallons of fruit juice and 7 gallons of soda.
