Melanie needs $18 more dollars. joseph has sold 5 boxes which means he has $20 and melanie has sold 3 which means she has $12 so 30-12=18
Answer:
infinite solution
Step-by-step explanation:
hello
we substitute b = 4a + 2 in the second expression
12a -3*(4a+2) = -6
<=> 12a -12a -6 = -6
<=> -6 = -6
which is always true
so there is infinite solution
hope this helps
Answer: $15.00 per person.
______________________________
Explanation:
______________________________
Given that there are "4 people" (that is, "Kianna and three friends");
____________________________________________________
and a total of "$58.49" ; to be divided equally among 4 (four) people;
______________________________
we are asked to <em><u>estimate</u></em> the amount that EACH person will pay.
______________________________
For an <em><u>ESTIMATE</u></em>, $58.49 is ABOUT $60.00; or "60 dollars". ;
and (60 dollars) / 4 = 15 dollars {$15; or $15.00}.
60/4 = 15; or 60/4 = (60÷2)/(4÷2) = 30/2 = 15.

Step-by-step explanation:
The amount that will be in the account after 30 years is $188,921.57.
<h3>How much would be in the account after 30 years?</h3>
When an amount is compounded annually, it means that once a year, the amount invested and the interest already accrued increases in value. Compound interest leads to a higher value of deposit when compared with simple interest, where only the amount deposited increases in value once a year.
The formula that can be used to determine the future value of the deposit in 30 years is : annuity factor x yearly deposit
Annuity factor = {[(1+r)^n] - 1} / r
Where:
- r = interest rate
- n = number of years
$2000 x [{(1.07^30) - 1} / 0.07] = $188,921.57
