Melanie and her cousin grace are arguing about who is
the faster swimmer. grace: 325 m in 5.5 min
melanie: 300 m in 5 min

Grace is the faster swimmer

Step-by-step explanation:

because Grace can do 25 m in .5 min, whereas Melanie can do 65 m in 1 minute, or 32.5 m in .5 min.

equation-

300 ÷ 5 = 60

325 ÷ 5 = 65

Grace is faster.

Step-by-step explanation:

To find unit rate, you divide the m by the minutes. so 325 ÷ 5.5 and 300 ÷ 5!

325 ÷ 5.5 = 59.09

and

300 ÷ 5 = 60

So Grace is faster since she took less time to do more distance!

step-by-step explanation:

f

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
