A man has 33 coins in his pocket, all of which are dimes and quarters. If the total value of his change is 630 cents, how many dimes and how many quarters does he have?

20 quarters and 13 dimes

Step-by-step explanation:

20 x 25 = 500

13 x 10 = 130

550 + 130 = 630

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
