If A$B = 2A + 3B + 20, then calculate the value of 7$3.

To calculate the value of 7$3 based on the given rule A$B = 2A + 3B + 20, we follow these steps:

Step-by-Step Calculation
Identify the values:
In the expression 7$3, we match the terms to the rule A$B:

A = 7

B = 3

Substitute into the expression:
Replace A and B in the formula 2A + 3B + 20:

2(7) + 3(3) + 20

Perform the arithmetic:

2 × 7 = 14

3 × 3 = 9

14 + 9 + 20 = 43
