Tomtit [17]

Answer:

US$ 132.45

Step-by-step explanation:

See attachment for the missing table.

Given:

Richard’s checking account balance at the beginning of the week = $57.34

Richard’s account balance at the end of the week from the given table:

Deposits of the week = US$ 163.75

Expenses of the week = Groceries + Credit card bill + Gas

Expenses of the week = 25.37 + 50 + 13.27

Expenses of the week = US$ 88.64

Richard’s account balance at the end of the week = Richard’s checking account balance at the beginning of the week + Deposits of the week - Expenses of the week

Replacing with the real values:

Richard’s account balance at the end of the week = 57.34 + 163.75 - 88.64

=US$ 132.4

Here is your first answer:

First find whats common which is 6:

-4×2=-8
3×2=6
-3×3=-9
2×3=6

Subtract -9 and -8
But use KCC which makes the equation...
-9+8=-1
-1/6

Here is your second answer:

First use KCC to Chang the equation into...

-3.9
-8.9

Then add:

9+9=18
=-1.28
