Let j = cost of one jumbo popcorn, and c = cost of one chocolate chip cookie.
Then, based upon the given info, 1j + 2c = $5.
Also, 3j + 5c = $14.50
Let's solve this system of equations using addition/subtraction:
Mult. the first equation by -3, to obtain -3j - 6c = -$15
Now add this result to the 2nd equation:
-3j - 6c = -$15
3j + 5c = $14.50
----------------------
-c = -$0.50, or c = $0.50. Since 3j + 5c = $14.50, subst. $0.50 for c
lets us find j:
3j + 5($0.50) = $14.50, so 3j = $12.00. Thus, j = $4.00.
Jumbo popcorn is $4/bag, and choc. chip cookies $0.50 each.
Hey there!
To solve this problem, first turn the mixed numbers to improper fractions then multiply 2 2/3 and 1 1/4 . . .
2 2/3 = 8/3
1 1/4 = 5/4
8 x 5 = 40
3 x 4 = 12
= 40/12
Simplify 40/12 . . .
40/12 = 3 1/3 <--------
The answer to your question is option B.
The bananas weighed 3 1/3 pounds.
Hope this helps you.
Have a great day!
Answer:32-10x

B. Shoe rental is $2.
Step-by-step explanation:
A. 4(3) + 2 = 14
