Alice spent some money on 60 stamps of two different values. The values of stamps could be 5-cents, 10-cents,20-cents and 30-cents. The total amount of money he spent was between $5 and $10. 2/5 of the tamps cost 4/3 times as much as the rest of the stamps.
a)What were the two values of stamps that she spent her money on?
b)How many stamps of each value did she buy?
c) How much money did she spend altogether?
