A store orders 22 boxes of light bulbs. Each box has 148 bulbs. Which is the best estimate of the total number of bulbs the store orders?

3,256bulbs

Step-by-step explanation:

From the question, we can see that;

Total number of boxes ordered = 22boxes

If each box contains 148 bulbs, then;

1 box = 148bulbs

To get the total bulbs we have we will say;

22boxes = x bulbs

solve this two expressions for x:

1box = 148bulbs

22boxes = x bulbs

Cross multiply

1×x = 22×148

x = 3256bulbs

Hence the best estimate of the total number of bulbs the store orders is 3,256bulbs

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
