Question

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?
StartFraction 1.55 over 1 EndFraction = StartFraction x over 3.5 EndFraction
StartFraction 1.55 over 1 EndFraction = StartFraction 3.5 over x EndFraction
StartFraction 1 over 1.55 EndFraction = StartFraction x over 3.5 EndFraction
StartFraction x over 1.55 EndFraction = StartFraction 1 over 3.5 EndFraction

Answer 1

Answer:

StartFraction 1.55 over 1 EndFraction = StartFraction x over 3.5 EndFraction

Step-by-step explanation:

$\frac{1.55}{1} = \frac{x}{3.5} \\ \\ \therefore \: x = 1.55 \times 3.5 \\ \\ \therefore \: x = \ 5.425 \\ \\\therefore \: x\approx \ 5.43$
