Guadalupe has some dimes and some quarters. She has no less than 18 coins worth at most $3.60 combined. If Guadalupe has 13 dimes, determine the maximum number of quarters that she could have.

Respuesta :

Answer:

10 quarters

Step-by-step explanation:

13 dimes is $1.30.

Subtract 1.30 from 3.60 which gives you 2.30.

4 quarters is a dollar so that is 8 quarters for 2 dollars and a quarter is 25 cents and 2 quarters are 50 cents so that's 10 quarters and you can't add one more because then it would be 3.75 but it's not more than 3.60
