sarah meeham blends coffee for tasti delight. she needs to prepare 160 pounds of blended coffee beans selling for $4.97 per pound. she plans to do this by blending together a high quality bean costing $6.00 per pound and a cheaper bean at $3.25 per pound. to the nearest pound, find how much high quality coffee bean and how much cheaper coffee bean she should blend

Answers

Given:
h = high quality bean ; costs 6 per pound
c = cheaper bean ; costs 3.25 per pound

160 pounds of blended coffee beans at 4.97 per pound

h + c = 160

6h + 3.25c = 160(4.97)
6h + 3.25c = 795.20

h = 160 - c

6(160-c) + 3.25c = 795.20
960 - 6c + 3.25c = 795.20
- 2.75c = 795.20 - 960
- 2.75c = -164.80
c = - 164.80 / -2.75
c = 59.92 or 60 pounds

h = 160 - c
h = 160 - 60
h = 100 pounds

Sarah must blend 100 pounds of high quality bean and 60 pounds of cheaper bean.

a tree is standing by the side of the building. 2/5th of the height of the tree is above the building level. the building is 9 metres high. what is the height of the tree?

Answers

If 2/5 of the tree is above the building, the other 3/5 must be down next to the building.

3/5(tree) = 9m

Multiply each side by 5/3 :

tree = (5/3) (9) = 15 meters

9 + ( 2 / 5 )*h = h =>45 + 2h = 5h => 45 = 3h => h = 45 / 3 => h = 15 metres.

Caitlin has a movie rental card worth $175. After she rents the first movie, the card’s value is$172.25. After she rents the second movie, its value is $169.50. After she rents the third movie,
the card is worth $166.75.
Assuming the pattern continues, write an equation to define A(n), the amount of money on the
rental card after n rentals.
Caitlin rents a movie every Friday night. How many weeks in a row can she afford to rent a movie,
using her rental card only? Explain how you arrived at your answer.

Answers

The equation A(n)= $175 –(n x $2.75) would define the amount of money on the
rental card after (n) rentals.

According to the pattern given, $2.75 will be deducted to the rental card every after Caitlin rents a movie. We can simply divide the amount of the card which is $175 by $2.75 which we presume the rental fee. From that, we can have a result of 63.63 rentals using her card. Therefore, there will be 63.63 weeks Caitlin can afford to rent a movie.
