Answer:
Step-by-step explanation 10 + 2.50d = 850
David starts with $10 and each day he earns $2.50. The d represents a variable and can be any number.
To find d you must solve the equation.
10 + 2.50d = 850
2.50d = 840 (subtract 10 from 850)
d = 336 (divide 840 by 2.50)
It will take David 336 days to save $850.
Around this time many people find home prices going up dramatically. Let's start with the X factor. If we know the starting is $120,000, the we know the initial velocity. To find the final but the very simple equation one may use is; P=(120000)^x\0.5

X is a unknown
Number you need to find what the total of all the angles will be and the solve for x
Answer: 0.02x
Step-by-step explanation:
The value of the cars the salesman makes is x in this instance.
The salesman makes a 2% commission on every sale so this can be represented by multiplying 2% by the value of the cars which in this case is x.
= 2% * x
= 0.02 * x
= 0.02x
If for instance he sells $40,000 worth of cars, his commission would be:
= 0.02 * x
= 0.02 * 40,000
= $800
Answer:
$3644675.9
Step-by-step explanation:
The initial investment is $100000. The interest rate is 12%.
We are asked to determine the final amount the investment will become after 30 years if the interest is compounded weekly.
The weekly interest rate is 
%.
Assuming 1 year equivalent to 52 weeks.
Hence, using the formula of compound interest the final sum will be
= $3644675.9 (Approximate)
