Answer:
70 cards
Step-by-step explanation:
Let A = the number of Andys cards
J = the number of Jons cards
Jon and Andy had a total of 560 trading cards
A+J = 560
After Jon gave 1/9 of his trading cards to Andy, they has an equal number of trading cards
J - 1/9 J = 1/9 J +A
Combine like terms
8/9 J = 1/9 J +A
Subtract 1/9J from each side
7/9J = A
Substitute this into A +J = 560
7/9J +J = 560
Combine like terms
7/9J +9/9J = 560
16/9 J = 560
Multiply each side by 9/16
9/16 *16/9 J = 560 *9/16
J =315
Jon originally had 315 cards
Now we need to find Andys cards
7/9J = A
7/9 (315) =A
245=A
How many more trading cards did Jon have that Andy in the beginning?
We need to take Jons cards and subtract Andys cards
J-A
315-245
70
Answer:
ratio of regular to diet soda = 16/9
Step-by-step explanation:
Jessica brought a cooler to the family picnic filled with 32 cans of regular soda and 18 cans of diet soda. This means
Number of cans of regular soda = 32
Number of cans of diet soda = 18
Total number of soda brought to the family picnic = number of cans of regular soda + number of cans of diet soda
= 32 + 18= 50
the ratio of regular soda cans to diet cans in the cooler= 32/18
Divide numerator and demo minator by 2, we have 16/9.
The fraction cannot be reduced further. So ration of regular to diet soda = 16/9
(25000-f)(.03)+.05f=1100
750-.03f+.05f=1100
750+.02f=1100
.02f=350
f=$17500
So Mary invested $17500 @ 5% and 7500 at 3% to earn $1100 in interest.
