Pleasee help!! “It costs $2.75 to buy 3/4 lb of grapes. How much would it cost to purchase 9.5 lbs of grapes? Explain or show yo

avanturin [10]

Answer:

$34.83

Step-by-step explanation:

First convert 3/4 to decimal form: 3/4 = 0.75

Create a proportion using similar rates:

$2.75 / 0.75 lb = x / 9.5 lb

where "x" represents the price of the 9.5 lbs of grapes we need to find.

Solve for x by multiplying both sides by 9.5 lb to isolate x completely

2.75 * 9.5 / 0.75 = x

Therefore x = $34.83
