One pound of grapes costs $1.55. which equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes? mc018-1.jpg mc018-2.jpg mc018-3.jpg mc018-4.jpg

Step-by-step explanation:

One pound of grapes costs $1.55 is given in the question.

We have to calculate the pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes.

Let the cost of 3.5 pounds of grapes = $x

So 1 pound of grapes will cost =

and it is already given that cost of 1 pound grapes = $1.55

so by equating both the costs of per pound grapes

or

Therefore, Equation showing the equivalent ratios will be

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
