A person has a weekly salary of x and gets a raise of 32% which is worth 50$ what is the weekly salary?
GuDViN [60]

Answer:

$156.25

Step-by-step explanation:

A good strategy in my opinion is the "finders" strategy

  50$  =  32%

   x      =  100%

First Multiply 100 by 50

100 x 50 = 5,000

Then Divide 5,000 with 32

5,000/32 = $156.25

If you want to check, then...

156.25 x 32 = 5,000

<em />

<em>x = $156.25</em>

Hope this helps!

A convenience sells two brands of orange juice. Brand A contains 8 fluid ounces and costs $1.28. Brand B contains 12 fluid ounce
White raven [17]

Answer:

Step-by-step explanation:

Brand A: 8(fl oz):$1:28

Brand B: 12:1.68

1)divide each side of the ratio

8:1.28 = 1:0.16

divide 8 by 8, and 1.28 by 8.

12: 1.68 = 1:0.14

divide each side by 12.

so, for brand A, for every one fluid oz it costs $0.16. for brand B, for every one fluid oz, it costs $0.14.

0.16-0.14= 0.02

$0.02 per fluid oz

happy to help:)
