Renata and david want to cover the walls in one room of their house with wall paper.
valkas [14]
For this case we have the following variables:
 P = area covered by a roll of wallpaper
 w = the total area of the walls
 n = number of rolls to buy
 We write the equation for n.
 You must take into account that you can determine this amount by dividing the total area between the area covered by each roll of paper.
 We have then:
 n = w / P
 
 Answer:
 
a formula that will help them determine how much wall paper they'll need to purchase is:

meriva
A]
Amount of earning per hour=$8.59
Amount of David's benefits=18/100×8.59=:1.5462
Amount that David earn per hour including benefits is given by:
8.59+1.5462=$10.1362

b]Amount that David earns in 35 hour a week will be:
(amount per hour)*(number of hours)
=8.59*35
=$$300.65

C] amount earned by David including benefits will be:
(amount earned in 35 hours)+(total benefits in 35 hours)
total benefits=1.5462×35=$54.117
thus total amount will be:
300.65+54.117

I am greater than 54 fewer tens than 90?
Lubov Fominskaja [6]
In all cases, we will let x represent the number.
1) 54 tens = 540
90 - 540 = -450
x > -450

2) x < 36 and x > 24
24 < x < 36

3) 8 tens and 5 ones = 80 + 5 = 85
x > 85

4) x > 27
x < 33
And the value in the ones place is less than the value in the tens place, so
30 ≤ x ≤ 32
