Answer: H- hot dogs
J- juice box
6h+4j=16.70
3h+4j=10.85
Elimination:
-6h-4j=-16.70
3h+4j=10.85
-3h=-5.85
H= 1.95
3(1.95)+4j=10.85
5.85+4j=10.85
4j=5
J=1.25
1.95 dollars for a hotdog and 1.25 dollars for a juice box

Answer: $4,365.10
Step-by-step explanation:
Ok, we know that:
The account starts with $2350
There is a simple interest of 3.75% (or 0.035).
Then after one year, the amount in the account will increase by 3.75%, this means that the amount will be:
$2350 + 0.035*$2350 = (1.035)*$2350.
After another year, we have the same increase (but applied to the new amount in the account):
(1.035)*$2350 + 0.035*(1.035)*$2350. = (1.035)^2*$2350
And so on.
You already can see the pattern here, the amount of money in the saving account after N years will be:
M(N) = $2350*(1.035)^N.
Now we can answer:
what is the balance of the account if it earns a simple interest of 3.75% for 18 years?
Just replace N by 18 in that equation:
M(18) = $2350*(1.035)^18 = $4,365.10
The discount is 50-14 = $36
% discount = (36/50)*100 = 72%
