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

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.

answer: the answer is   graph (a)
