Answer:

\$20

Step-by-step explanation:

Let

x-----> the cost of his lunch

y----> the cost of his dinner

we know that

x+y=872-136-210-500

x+y=26 -----> equation A

x=0.3y ---> equation B

substitute equation B in equation A

0.3y+y=26

1.3y=26

y=\$20 -----> the cost of the dinner

You anticipate that a $2000 investment in a local business will pay an average of 4% interest in each of the next 5 years. Deter
Dovator [93]
Since this is a problem in exponential growth/decay, y = ab^x is the formula that will be used to solve this problem.

The initial value, "a", is the value you start out with and in this case, it is $2000. 

The growth/decay factor is what "b" represents, and it is 4%. We need to change the percentage into a decimal, so we will take the percent symbol, change it into a decimal, and move it two places to the left. This is make it 0.04. The problem also mentions interest, implying an exponential growth. Therefore, you will add 0.04 by 1: 1+0.04 = 1.04. 

The "x" represents an amount of time. It is 5 years. The equation should be written like this: 

y = 2000(1.04)^5
y = 2433.30. When rounded to the nearest dollar, it is $2433.
