Answer 2

Answer: To find out how many weeks it will take for Alex to have enough money to buy the smartphone, we need to use the following formula:

weeks=rategoal−saved​

where:

goal is the amount of money he needs to buy the smartphone, which is 550$

saved is the amount of money he has already saved, which is 250$

rate is the amount of money he saves per week, which is 30$

Plugging in these values, we get:

weeks=550−250​/30

Simplifying, we get:

weeks=300​/30

Dividing, we get:

weeks=10

Therefore, it will take Alex 10 weeks to have enough money to buy the smartphone. I hope this helps.
