Elina is gathering up change she has saved. she has a total of $2.60. all of her change is in either nickles, dimes, or quarters. she has twice as many dimes as quarters and two less quarters than nickles. if the number of quarters elina has is represents by the variable n, write an equation that models this problem and solve it for the number of each type of coin. (i keep getting 1.15 but it doesn't make sense if n=1.15 when n is how many quarters there are so .)
