Atool rental store charges a flat fee of $10 to rent a chain saw, and $6.25 for each day, including the first. write an equation that expresses the cost of y of renting this saw for x days.

Step-by-step explanation:

flat fee of 10 bucks...and 6.25 for each day

x = number of days

y = total cost

y = 10 + 6.25x or u could also write it as : y = 6.25x + 10either way is the same

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
