Answer:
The approximate % increase was around 33%
Step-by-step explanation:
Divide 24 by 18 and you convert the decimal into a percent which is just multiplying it by 100
Solution:
The Ordered pair of the function is
x : 0 1 2 3 4 5
y: 13 21 29 37 45 53
(a) 
Slope between two points are same.So,the function Represented in terms of ordered pairs Linear.
(b) As, you can each Successor of x values is obtained by adding 1 to it's Predecessor.
and , each Successor of y values is obtained by adding 8 to it's Predecessor.
(c) Taking any two ordered pairs , (0,13) and (1,21) we can find an equation of line passing through these 5 points (2,29),(3,37),(4,45),(5,53)
Equation of line passing through passing through two points
is given by
= 
= 
→ y -13 = 8 x
→ y = 8 x + 13
So, Y intercept = 13
Borrowing money is a way to purchase something now and pay for it over time. But, you usually pay “interest” when you borrow money. The longer you take to pay back the money you borrowed, the more you will pay in interest. It pays to shop around to get the best deal on a loan.
Okay 39 is 150% of what number? so like remember whenever you see percent you have to divide by 100
so let's start
First. we have 150% so let's divide 150%/100=1.5
Second. you will multiply 1.5*39= 26%
and you can also do it like easy way.
39/150=0.26
0.26/100=26
39 is 26% of 150
hope i help :p
40% = 40/100 = 0.40
Find 40% of 20
20 * 0.40 = 8
Solution: 8 students traveled
