Answer:
1/1296
Step-by-step explanation:
The correct way to solve this equation would be:
7=5+3(x-4)
Distribute the Brackets.
3*x=3x
3*4=12
7=5+3x-12
Add like terms.
7=-7+3x
Add 7 to both sides.
(7)+7=(-7+3x)+7
14=3x
Divide both sides by 3.
(14)/3=(3x)/3
4.6667 or 14/3 =x
Both answers are incorrect.
Some the significant mistakes:
-Didn't follow BEDMAS
-How did 7=8(x-4) turn into 78=x-4?
Hope this helps.

The correct answer is A: $3135.84
To find the total balance on the account all we need to do is use the compound interest formula.
It would be:
y = 5000(1 + 0.0325/12)^(15*12)
Evaluating this will give you a total of 8135.84
Now, just subtract off the original 5000 and you have the amount of interest.
Multiply 75 by the number of surfboards sold to get 75x add that to what he makes giving lessons:
250 + 75x
He wants to earn at least 500 so the equation has to be greater than or equal to 500:
Answer: 250 + 75x > equal to 500
