Answer:
-60
Step-by-step explanation:
Raul has 56 bouncy balls
he puts the balls into red gift bags and green gift bags
so lets say he puts x number of balls into green gift bags
then we are told that he puts three times as many balls into red gift bags as he puts into green gift bags
so the number of balls he puts into red gift bags is - 3 * x = 3x
the total number of balls = 56
so we can write the following equation
x + 3x = 56
4x = 56
x = 56/4
x = 14
therefore the amount of balls he puts into green bags is - 14 balls

This is the point where 
From the graph, we have the following as the x-intercepts:


Because the curve crosses the x-axis at the above points
Normally 7 envelopes but on rare occasions, there may be more due to If the packages are filled with Envelopes. Also depending on if the 7 packages are boxes of envelopes, and in that case, 140 envelopes times 7, which would be 980 envelopes in the 7 packages. 140 * 7 = 980.
