you have $ 1.55 in dimes and quarters. find all the possible combinations of coins that you might have
i got;
1) 1 quarters 13 dimes
2) 3 quarters 8 dimes
3) 5 quarters and 3 dimes
is this right 3 ways?
Yes, you're right.
Yes, you are correct. There are indeed three possible combinations of coins that can add up to $1.55. These are:
1) 1 quarter and 13 dimes
2) 3 quarters and 8 dimes
3) 5 quarters and 3 dimes
Well done!
Yes, your 3 possible combinations of coins are correct. To arrive at these combinations, you can use a systematic approach by considering different numbers of quarters and dimes that can add up to $1.55.
Let's break it down:
1) 1 quarter and 13 dimes:
- Value of 1 quarter: $0.25
- Value of 13 dimes: 13 * $0.10 = $1.30
- Total value: $0.25 + $1.30 = $1.55
2) 3 quarters and 8 dimes:
- Value of 3 quarters: 3 * $0.25 = $0.75
- Value of 8 dimes: 8 * $0.10 = $0.80
- Total value: $0.75 + $0.80 = $1.55
3) 5 quarters and 3 dimes:
- Value of 5 quarters: 5 * $0.25 = $1.25
- Value of 3 dimes: 3 * $0.10 = $0.30
- Total value: $1.25 + $0.30 = $1.55
Therefore, your three ways of making $1.55 using combinations of dimes and quarters are correct.
1 quarter=25
1 dime=10
13x10=130 or 1.30+25=155 or 1.55
25x3=75 or .75+80=155 or 1.55
25x5=125 or 1.25+30=155 or 1.55
Correct :)
