Answer:

Step-by-step explanation:

9, 13, 17, 21, 25

We are adding 4 each time

9+4 = 13

13+4 =17

17+4 = 21

The common difference =4

a1 = 9

The formula is

an = a1+d(n-1) where n is the term number

an = 9+4(n-1)

We want the 10th term

a10 = 9+4(10-1)

= 9+4(9)

= 9+36

= 45

Julio is paid 1.2 times his normal hourly rate for each hour he works over 31 hours in a week. Last week he worked 41 hours and

xxTIMURxx [149]

Let Julio's normal hour rate is $x .

So we have

$31x + (41-31)*1.2 x = 550.40
\\
31x +10*1.2x = 550.40
\\
31x+12x = 550.40
\\
43x= 550.40
\\
x = \frac{550.40}{43}=$12.80$

So Julio's hourly rate is $12.80.

And this is reasonable , since working 41 hours at a rate of $ 13 per hour is

$=41(10+3)=410+123=533$

is close to 550.40 .

Nathan, a tutor, buys 5 calculators for $7.50 each at a store, planning to provide one to each of his clients. However, the next

harkovskaia [24]

Answer: 5 (7.50-3 )

Step-by-step explanation:

Given: Previous price of calculator = $7.50

Number of client =5

Total price = (Number of calculators) x (Price for each calculator)

Total price of 5 calculators = (5 x $7.50)

New price of calculator = $5.00

Number of client =3

Total price of 3 calculators = (3 x $5)

Price will receive = (Total price of 5 calculators) -(Total price of 3 calculators )

= (5 x $7.50) - (3 x $5)

= 5 (7.50-3 )

Required expression: 5 (7.50-3 )
