If he decides to save 10% he decided to save 38.75 since 387.50×.10 is 387500 (move decimal 4 times to figure out what the percentage of 387.50 is since the $ already has 2 numbers after the decimals and so does .10 which =38.75 this is what he saves so subtract this from 387.50 to find out what he has left to spend
387.50-38.75= 348.75
7800 because it grows 300 per 2 hours so 3000 + 4800 = 7800

Step-by-step explanation:
Given that:
Steve divided 5/8 of a box evenly among 5 bottles. To determine the amount of baking soda added;
Then, mathematically:
Answer:
0.917915
Step-by-step explanation:
Exponential distribution is expressed as it follows
F (y,λ) = 1 – e ^(- λ(y)
)
Where λ is equal to 1/ population mean
So λ = 1/2.8 = 0.357
Let y be the length of time a costumer wait on hold
Now, let´s find the value for y = 7 minutes, which is the proportion of costumer that wait on hold
P (y<7) = 1 – e^(- .357*(7)
)
P (y<7) = 0.917915
