Monica has been saving her spare change. So far, she has saved 40 coins for a total of $6.25. Some of the coins are quarters (25 cents), and the rest are dimes (10 cents).
How many of each coin does she have? Let the number of quarters = q and the
number of dimes = d.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

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

any options?
