However, before luke can buy the iPad, he must give his sister $55 that he owes her. For how many week will Luke need to deposit money into his savings account before he can pay back his sister and buy the iPad

Answer:Luke needs to deposit money into his savings account for 10 weeks before he can pay back his sister and buy the iPad.

Step-by-step explanation:

The cost of the iPad that Luke wants to buy is $575

before Luke can buy the iPad, he must give his sister $55 that he owes her. This means that the total amount of money that he must save would be 575 + 55 = $630

He will be able to deposit $65 into a savings account when he receives his paycheck each Friday.

Let x represent the number weeks it takes him to save enough money in his account. Therefore, the total amount that he saves for x weeks would be 65 * x = 65x

Therefore,

65x = 630

x = 630/65

x = 9.69
