Answer:

The linear equation which models this situation is given by:

y = 60x + 25

Step-by-step explanation:

It is given that:

A plumber charges a consultation fee of $25 then charges $60 an hour.

Let x represents the number of hours.

and y represents the total fee for x hours.

This means that x is an independent variable since the value of such a variable is to be assigned and y is the dependent variable since the value of y is obtained corresponding to different values of x.

Hence, we have:

The total cost will be:

y= 60x+25

Complete Question

Let P (n) be the statement that a postage of n cents can be formed using just 4-cent stamps and 7-cent stamps. The parts of this exercise outline a strong induction proof that P (n) is true for n ≥ 18.

Show statements P (18), P (19), P (20), and P (21) are true, completing the basis step of the proof.

Answer:

P(18) is true

P(19) is true

P(20) is true

P(21) is true

Step-by-step explanation:

a. When n = 18

18 cents can be formed using two 7cents and one 4cents

i.e. 2 * 7 + 4 = 18

So, P(18) is true

b. When n = 19

19 cents can be formed using one 7cents and three 4cents

i.e. 1 * 7 + 3 * 4 = 19

So, P(19) is true

c. When n = 20

18 cents can be formed using five 4cents

i.e. 5 * 4 = 20

So, P(20) is true

d. When n = 21

18 cents can be formed using three 7cents

i.e. 3 * 7 = 21

So, P(21) is true

Too lazy to format so here

R = 20D =

R = 20(6) =

120 = 20(6)

r = 120 = the days it cost to rent bike

so expensive

Alex777 [14]

Well, if Sameer's plum was 32 calories, and we know his total snack was 56 calories, all we have to do is:

56-32=24

24 / 4 = 6

Sameer ate one plum (32Kcal) and 6 strawberries (4Kcal each)
