do the opposite of what you did in reverse order.

so add 100 and divide by 2 in that order.

Answer:

2 × 80 + 100 = 260

Step-by-step explanation:

The question says Ahmed

  • doubled his savings: we must multiply his savings by 2, hence 2s
  • then deposited another hundred dollars: we must add 100 dollars, hence + 100

So the expression for his current amount will be:

Current amount = 2 s + 100

where s represents the initial savings

Given that s = 80 , the current value will be:

Current value = 2 × 80 + 100 = 260
