Answer:
YESSSSS
Step-by-step explanation:
The answer to this question is 1:11.
Answer:
The required expression is s = m + n
Step-by-step explanation:
Let m be the number of index cards stuffed in the envelopes and n be the number of extra index cards.
Let s be the total number of index cards.
Then, s = m + n represents the number of index cards the boys started with.
For Marty,
He has 15 stuffed envelopes and 4 extra index cards.
So, m = 15, n = 4
Therefore, s = 15 + 4 = 19
Marty started with 19 cards.
For Stewart,
He has 12 stuffed envelopes and 6 extra index cards.
So, m = 12, n = 6
Therefore, s = 12 + 6 = 18
Steward started with 18 cards.
$1 has 4 quarters
so $2 has 2 x 4 = 8 quarters
