Answer:
C. 18.75
Step-by-step explanation:
3 + 5 + 3 + 6 = 17
30 + 30 = 1
17 + 1 = 18
45 in decimal form is .75
the answer is 18.75
Answer:
c=35
Step-by-step explanation:
3c - 15 = 90
+15 = +15
3c = 105
////////////
3. 3
c = 35
So, from this information you can set up two equations:
0.1x + 0.25y = 5 dollars and
x + y = 41 coins
where x = how many dimes and y = how many quarters
Solve for either x or y in the second equation, so x = 41 - y and then plug this in for x in the first equation to get:
0.1(41 - y) + 0.25y = 5
4.1 - 0.1y + 0.25y = 5
4.1 + 0.15y = 5
0.15y = 0.9
y = 6
We solved for y and now we know there are 6 quarters, so you can plug this into the second equation to solve for x. We fine that we have 35 dimes. You can always your work by plugging what you get for x and y back into the equations.
