The integer number that represents the changing in his account balance from beginning to end is of -20.
<h3>Which numbers belong to the set of integer numbers?</h3>
Non-decimal numbers, either positive or negative numbers, also zero, belong to the set, which can be represented by:
Z = {..., -3, -2, -1, 0, 1, 2, 3, ...}
A change can be represented by the <u>final value subtracted by the initial value</u>. For this problem, we have that:
- The initial balance is of $20.
- The final balance is of $0.
Hence the change in the balance is:
0 - 20 = -20.
And the integer is -20.

1(Identifying):
Tomatoes-x--$3 per lb
Mushrooms- 1/3 x-- $10 per lb
Peaches- x+1-- $6 per lb
2(Equation):
3x+6(x+1)+1/3x*10=80
3x+6x+6+10/3 x=80
12 1/3 x= 74
x=74÷(12+1/3)
Step 3(Final Equations):
74*3/37=6=tomatoes
Meaning...
6+1=7=Peaches
6/3=2= mushrooms
Answer:
