Answer:
The answer to your question is Advance = $35 and same-day = $40
Step-by-step explanation:
Advanced = a
Same-day = s
Equations
a + s = 75 ----- (I)
20a + 35s = 2100 ----- (II)
Process
1.- Solve the equations by elimination.
Multiply equation I by -20
-20a - 20s = -1500
20a + 35s = 2100
Simplify
0 + 15s = 600
Solve for s s = 600/15
s = $ 40
Substitute "s" in equation I to find "a"
a + 40 = 75
Solve for a
a = 75 - 40
a = 35
Answer:
41/120
2/3 of 120 is 80, you have 40 left
2/5 of 40 is 16, you have 24 left
1/8 of 24 is 3.
Subtract those totals and you will get 41 leftover.
Step-by-step explanation:
4 9/10 + 3 7/10
49/10 + 37/10(turned into an improper fraction
86/10 ( both figures added )
=8 6/10(result)
