A small juice company spends $1200 per day on business expenses plus $1.10 per bottle of juice them make. They charge $2.50 for
Greeley [361]
Cost price per bottle of juice = $1.10 
Selling price per bottle of juice = $2.50 
Profit per bottle of juice = $2.50 - $1.10 = $ 1.40 
Let B be the number of bottles needed to sell in one day in order to equal its daily costs. 
$1200 = $1.40B 
857.14285714285714 = B 
858 = B (round off to the nearest bottle) 

The company must sell 858 bottles of juice in one day in order to equal its daily cost. 

Hope this helps! =)

Plums are 6 for $1.50, and a sign by the apples that are 5 for $3.00. What is the total cost of buying 2 plums and 2 apples?
Doss [256]

Answer:

The answer is $1.70

Step-by-step explanation:

If 6 plums are $1.50 you would divide $1.50 by 6 to get the unit cost, $.25. Then you do the same thing for the apples. $3.00 divided by the 5 apples is $.60. Now you need to multiply both unit costs by 2 then add them together to get $1.70

(plums)  $1.50 / 6 = .25

(apples) $3.00 / 5 = .60

(plums)  .25 x 2 = .50

(apples) .60 x 2 = $1.20

$1.20 + .50 = $1.70

Hopefully I could help!!
