show your work so i can see how you did it.

5 quarters 2 dimes and 7 pennies

You know that the quarters and dimes together equal to the pennies, do you divide the number of coins by half, from there you find how much money worth you have of quarters and dimes, using that you use : 0.25X+0.1Y=1.45, from there you common factor by 0.05 and you divide both sides by 5 cents and you get 5x+2y=29, from there you see that you have 5 quarters, 2 dimes and 7 pennies
