Question

Navid had $72 in her savings account.

Answer 1

Answer:

9 weeks.

Step-by-step explanation:

First, find how many dollars Navid needs to save.

288-72= 216

Then, divide how much money that is needed by the number of dollars that are saved per week.

216/24= 9

Then tie it up into an equation:

(288-72)/24= x

x=9

Answer 2

Answer: After 9 weeks

Step-by-step explanation: Using what is given she has 72$ and she needs 288 and if she makes 24$ per week we can write the equation 72 + 24x = 288 with x being the amount of weeks. Then we can subtract 72 on both sides leaving 24x = 216. Then we will have to divide 24 on both sides to get  x by itself. 216/24 = 9 so it will take 9 weeks. You can check by putting this equation in a calculator since you can't type 72 + 24x = 288 you can use y = 72 + 24x - 288 since the other side will  be zero look for when y is zero x = 9.
