A is your answer
We can cross multiply using x/70=30%/100
Solving it we get:
100x=2100 (70 times 30)
x=21
So we get a, 21 as your answer.
I hope this helped!
First, determine the weight of 330 cans with the given conditions,
(330 cans) x (4 lbs / 100 cans) = 13.2 lbs
Then, the price is determined by multiplying this weight to the price that the recycling center is paying,
(13.2 lbs) x (25 cents / lb) = 330 cents = $3.3
Thus, Robert will be paid $3.3.
Multiply the dot is always multiply
I think it would be the last one from my calculations im not positive but its what makes sense.
3/5x ≤ 10
5(3/5x ≤ 10)
3x ≤ 30
3x/3 ≤ 30/3
x ≤ 10
