Answer 1

Please read, it's not too difficult, it's just a lot of words

Answer 2

My guess is\[700\times r \ge3000\] which got me 4, that doesn't sound right ,so I want my answer to get checked

Answer 3

Answer 5

the equation would look like this
\[28(10r + 5(5)) \ge 3000\]
\[280r \ge 3000 - 700\]
\[r \ge \frac{2300}{280}\]

Answer 6

Oh, thank you so much! would it come out as 8 ?

Answer 7

no you would need to round up... if its 8 then total money will be less than 3000

Answer 8

And how?

Answer 9

?? what is 2300/280

Answer 10

Smartcow, does that mean division? @dumbcow

Answer 11

@Spicytaco1 what does he/she mean?

Answer 12

yes divison

Answer 13

I did division and got 8 when rounded

Answer 14

what did you get before rounding

Answer 15

8.214

Answer 16

ok
\[r \ge 8.214\]
since r must be greater, then you must go up to 9, not down to 8

Answer 17

so the answers is 9?
