Ash just got a job at tom’s diner. At the end of her shift she had 28 coins, some quarters and some dimes. If her total is $5.80, how many quarters and dimes she has in total?

Answer 1

Hi Angel. Look at what you know in this problem...you have quarters and dimes. Your total number of coins is 28. Turn that into a math sentence or Q + D = 28

You also know that the total value of quarters and dimes =$5.80. Turn that into a math sentence or

.25 Q + .10 D = $5.80 Now you can use the first sentence to sub into the second and solve!
