Answer:
a. 2x -3
b. 7
Step-by-step explanation:
a. The expression that represents the difference is sales between the two sales will be:
9x - (7x + 3) = 9x - 7x - 3 = 2x - 3
b. What we do here is to simply substitute the value of 5 for x
mathematically, we have to substitute the value of 5 in the expression above
We have this as:
2(5) -3
= 10-3 = 7
D option is correct answer.
Lets solve for the finance charge in dollars when Tim agreed to pay $36 for 12 months. We formulate an equation by enumerating the following:
1.) Total amount that Tim paid for the DVD player is $36 times 12 months is equal to $432.
2.) Total amount paid is the summation of DVD player original price plus the result of multiplication of finance percent charge and original price.
Equation is $365+($365x%charge)=$432.
Solve for % charge,
%charge = ($432-$365)/$365
%charge =0.1834 or 18.4%
Therefore, the finance charge in dollar is $67.

The formula would be y = 1,236,000(1.3)^t
After 10 years, the population would grow to become 17,039,309.59 people. You can round up to 17,039,310 people if the question asks to round to the nearest person.
