Answer:
option 2
Step-by-step explanation:
I'm using the assumption that he will have to pay for 4 years (as stated in the problem). You will need the length of time he would be making payments (in months) or the total cost of the vehicle to solve this problem.
4 years = 12 x 4 = 48 months
Option 1: 500 + 195 (48) = 500 + 9360 = 9,860
Option 2: 4,000 + 55 (48 - 6) = 4,000 + 55 (42) = 4,000 + 2310 = 6310
If he can wait six months, it will save him about $3,500 to go with Option 2.
Using the combination formula, it is found that you can select 2 boys and 5 girls in 2,520 ways.
In this problem, Joao and Elisa would be the same team as Elisa and Joao, hence the order is not important and the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:

In this problem:
- 2 boys are selected from a set of 6.
- 5 girls are selected from a set of 10.
Hence:

You can select 2 boys and 5 girls in 2,520 ways.

Y = 2x + 2
that is your slope intercept equations
Answer: the last one
Step-by-step explanation: because 7 times 24 equals 168 and x would be 21 so 21 times 8 equals 168.
