First off please don't be so rude, Your wording is quite brash and unthankful.

21 for the last box

For the top one its (7+21)÷2=14

and what It wants you to solve for be is unclear but its either 21, 28 or 14

Step-by-step explanation:

So lets work backwards here, she is left with 14 boxes after the fire, and it states that the fire took half of the boxes she had, so the oppisite of taking away half is multiplying by 2. So that gets us to 28, subtract the 7 she got at the start of the week and you get 21.

Answer for the second one:

So its 238 + 29 =267

Next box is 34 because 238 divied by 7

34 for the last box

X = standard and y = high quality

2.4x + 4.8y = 2880
y = 2x

2.4x + 4.8(2x) = 2880
2.4x + 9.6x = 2880
12x = 2880
x = 2880/12
x = 240 <== there were 240 standard version downloads

y = 2x
y = 2(240)
y = 480...there were 480 high quality version downloads
