Molly Wilkins · Answer 1

he has 5d+3q

Step-by-step explanation:

since every d is. 10 and every q is. 25 the equation can be changed to 5 (.10) + 3 (.25) which is equal to. 5+.75 which adds up to 1.25

i did this by assuming that the amount of d is 8 at first, then change one of the 8 d to a q which will give you 7d+q, then assume another d is a q which will give you 6d+2q, repeat this until the amount of d and q add up to 1.25
