Question

Ahmed doubled his savings, then deposited another hundred dollars. Let s represent the amount he originally had in savings. Which shows an expression to represent his current amount and the current value of his account if s=80?
s/2 + 100 when s=80 the latest balance of Ahmed’s savings is $140
2s + 100 when s=80 the latest balance of Ahmed’s savings is $260
s^2 + 80 when s=80 the latest balance of Ahmed’s savings is $6,480
s^2 + 100 when s=80 the latest balance of Ahmed’s savings is $6,500

Answer 1

2s + 100 when s=80 the latest balance of Ahmed's savings is $260

because he doubles his savings you times s by two and then add 100 because he deposited this after.

Answer 2

Answer:

B. 2s + 100 when s=80 the latest balance of Ahmed’s savings is $260

Step-by-step explanation:

We are given that the savings = $s and current amount  $c.

Now, Ahmed has doubled his savings. This means that the new savings = $2s

Also, he had deposited $100.

So, the current amount of Ahmed is given by c = 2s + 100.

Moreover, if the savings is $80 i.e. s = 80, the current amount is,

c = 2 × 80 + 100

i.e. c = 160 + 100

i.e. c = 260

So, the current amount if savings is $80 is $260.

Hence, the expression for current amount is 2s + 100 and if s = 80, the current amount is $260.
