Answer: 12 weeks
Step-by-step explanation:
If Keith wants tgo have at least 200 in his account at the end of summer you need to minus it from the original 500 to make a new total.
Now you will have $300 to work with.
Since Keith needs $25 a week you will divide your new total ($300) by 25 and it will give you the number of weeks he can sustain this budget.
300/25=12

Question:
At a carnival, food tickets cost $2 each and ride tickets cost $3 each. A total of $1,240 was collected at the carnival. The number of food tickets sold was 10 less than twice the number of ride tickets sold.
How many of each type of ticket were sold?
Answer:
350 food tickets and 180 ride tickets were sold
Solution:
Let "x" be the number of food tickets sold
Let "y" be the number of ride tickets sold
Cost of 1 food ticket = $ 2
Cost of 1 ride ticket = $ 3
The number of food tickets sold was 10 less than twice the number of ride tickets sold
Number of food tickets sold = twice the number of ride tickets sold - 10
x = 2y - 10 -------- eqn 1
A total of $1,240 was collected at the carnival
Therefore, we frame a equation as:
number of food tickets sold x Cost of 1 food ticket + number of ride tickets sold x Cost of 1 ride ticket = 1240
2x + 3y = 1240 ------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 1 in eqn 2
2(2y - 10) + 3y = 1240
4y - 20 + 3y = 1240
7y = 1260
Substitute y = 180 in eqn 1
x = 2(180) - 10
x = 360 - 10
Thus 350 food tickets and 180 ride tickets were sold

If you have a lot of Pythagorean triples memorized, then you'd probably know immediately, but if not, then you can use the Pythagorean Theorem to calculate each one:
A.: 7^2+9^2=49+81 which is not equal to 13^2, or 169
B.: 5^2+12^2=25+144 which is not equal to 14^2, or 196
C.: 8^2+15^2=64+225=17^2=289
D.: 9^2+12^2=81+144 which isn't equal to 14^2, or 196
Therefore, the correct answer is C.
