Sagot :
Answer:
Step-by-step explanation:
Equations
Let the dimes be x
Let the quarters be y
x + y = 19 (1) Multiply this equation by 0.1
0.1x + 0.25y = 3.10 (2)
0.1x + 0.1 y = 1.90 (3) Subtract 3 from 2
0.15y = 1.20 Divide by 0.15
0.15y/0.15 = 1.20/0.15
y = 8
x + y = 19
x + 8 = 19 Subtract 8 from both sides
x+8-8 = 19-8 Combine
x = 11
