Answer:
-650
Step-by-step explanation:
The present value of the investment is $6000.
According to the statement
Principal amount = $500
and Return amount = 10.5%
Time period = 20 years.
Now we find the present value of money then
By the formula
PV = P[1-(1+r)^n]/r
PV = 500[1-(1+0.10)^20]/0.10
PV = 6000
So, The present value of the investment is $6000.

I'm not going to do the entire question, but I'll do the first part.
For the first part, you have to set up an inequality. Use context clues, such as
no more than (the one used in this sentence) to figure out what the symbol should be for the inequality.
In this case, because it is NO MORE THAN 6400, it would be:
6400

250r + 475p
where r represents the # refrigerators, and p represents the # pianos
Now that you have the equation, make the graph, then for the 3rd part, plug in 12 and 8 to r and p to see if it keeps the inequality true.
Hope this helps! :)

The equation representing the given statement is ~
The least number of lawns that he can cut and buy the computer is 10 lawns ~

Total savings should be greater or equal to $ 820 in order to buy the computer,
And his total savinga is equal to ~
Money he saved + money got from cutting lawns.
let's assume the lawns cut by Tyrod be x,
Money earned by cutting lawns is equal to
- total number of lawns cut × $50
total savings is equal to ~
hence,
by solving for " x (number of lawns cut) " we get ~
Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is
