You can proceed like this,

650 kb for a pic
and 2200kb for song ( 650 + 1550)

total= 18150 kb and 16 files

so, 650 kb each in both pic and song = 16 * 650= 10400

remaining = 18150-10400 = 7750 , which is contributed by additional 1550 of songs that is
7750/1550 = 5

so, a total of 5 songs and 11 pictures were sold..

hope it helped

Sandra bought a tube of toothpaste for $1.89, shampoo for $3.19 and a jar of peanuts for $2.29 from the local supermarket. Using

uranmaximum [27]

To find the total cost, you need to add these numbers together

$1.89 + 3.19 + 2.29 = 7.37$
you get 7.37 as your answer, but you need to round this to the nearest whole number.

rounding 7.37 will make it 7.

the total cost is about $7

3 + 1 < 10 solve, then graph the solution

ryzh [129]

3 + 1 < 10

There's no question there, and nothing to solve. That's a simple statement
which, after simplifying it slightly, says " 4 < 10 ".

A statement with which, I'm sure, we can all agree.
