The statement that best gives the reasons that a data usage bill for a smart phone is an essential (variable) expense is: a. It is an obligation to pay, but the spender has some control over its amount Variable expense are the expense that happen depending on how much resource that you use, which is simialrt to the phone billing system

A) It is an obligation to pay, but the spender has some control over its amount.

Step-by-step explanation:

An essential expense is an important expense required for living. These expenses can be fixed or variable. Fixed expense remains same but variable expense changes.

Here, in the given scenario, the data usage bill is variable as it depends completely on the usage. If the user is using more data, the bill will be more. If the data usage is lower, the bill will be less.

Therefore, option A is the right answer.

You can do this by finding the prime factors of 2352

2352 = 2 * 2* 2 * 2 * 3 * 7 * 7

We see that its not a perfect square because there is only one 3. If we multiply by another 3 we will have a perfect square.

2*2*2*2*3*3*7*7 = 7056 which is the smallest perfect square as required.

square root of 7056 = 2 *2 * 3 * 7 = 84 answer
