Answer:
A
Step-by-step explanation:
We are told that the number at the unit place is 3 less than the number at the tens place.
So if the number at the units place is b, then the number at the tens place is 10(b+ 3)
So the number is thus;
10(b + 3) + b
= 10b + 30 + b = 11b + 30
If you have 1 nickle, how many quarters do you have? (3)
If you have 4 nickles, you have 3 times as many quarters (3)(4) = 12
If you have n nickles, then you have 3n quarters so 3n = q, you have a slightly different equation.
If you fix this equation and use substitution like you did, you can get the right answer; you can also try to work in the other information that you have - converting all coin values to cents
5n + 10d + 25q = 460
3/8 of 16 = (16 / 8) x 3
= 2 x 3
= 6
2/3 of 6 = (6 / 3) x 2
= 2 x 2
= 4
