Step-by-step explanation: density = mass / volume
Density is 240 kg / 8 m³
For this case we have the following equation:

When it's 5 a.m. then x = 0
Therefore, when it is 7 a.m. then x = 2.
Substituting x = 2 in the equation we have:

Rounding to the nearest whole number:
Answer:
the best estimate for the number of people in line at 7 a.m. is:
y = 40
Answer:
Store A has a better deal because $402.90 is less than $404.10.
Step-by-step explanation:
<u>Store A</u>
The $25 off coupon reduces the price to ...
$499 - 25 = $474
The discount from this amount is 15%, so is ...
$474 × 0.15 = $71.10
The final amount paid is then ...
$474.00 -71.10 = $402.90
(<em>Side note</em>: you can select the correct answer at this point, because only one answer shows this value.)
___
<u>Store B</u>
After the $20 off coupon, the price is ...
$469 -20 = $449
The additional 10% discount amounts to ...
$449 × 0.10 = $44.90
So, the final price is ...
$449.00 -44.90 = $404.10
___
Now, you know that Store A offers the better price because $402.90 is less than $404.10.
