Answer: Choice A</h3>
0.10d + 0.05n = 2.25
d = 2n
================================================
Explanation:
n = number of nickels
d = number of dimes
we have twice as many dimes as nickels, so we could have something like 18 dimes and 9 nickels. Algebraically we would write d = 18 and n = 9. The equation that fits this is d = 2n. The answer is between A and B at this point.
We rule out choice B since the 0.05d is incorrect. It should be 0.10d to represent the total value of all the dimes.
Choice A is correct
d = number of dimes
0.10d = value of all the dimes in dollars
n = number of nickels
0.05n = value of all the nickels in dollars
0.10d + 0.05n = total value from both coins combined
2.25 = total value from both coins combined
0.10d + 0.05n = 2.25
Answer:
Median: 36 and 1/7
Mode: 45
Range: 25
Step-by-step explanation:
33 + 45 + 38 + 27 + 45 + 20 + 45
253 ÷ 7 = 36 and 1/7
1 33
3 45s
1 38
1 27
1 20
The mode is 45.
Largest number: 45
Smallest number: 20
45 - 20 = 25
