PLEASE HELP ME I'VE BEEN STUCK ON THIS FOR SO LONG a track has an inner loop that is 3/8 mile and an outer look that is 1/2. on Saturday, Melanie ran 2 1/4 miles on the inner loop. on Sunday, she ran the same distance on the outer loop.

how many laps did Melanie run around each loop?

6 laps around the inner loop, 4 1/2 laps on the outer loop, im not entirely sure but this is my best guess.

Step-by-step explanation:

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

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
