Answer:
Kailee bought 26 of 49-cents stamps and 10 of 21-cents stamps.
Step-by-step explanation:
Given:
Total Money paid for stamps = $14.84
Let the number of 49-cents stamps be x.
Also Let the number of 21-cents stamps be y.
Now Total Money paid is equal to sum of number of 49-cents stamps and number of 21-cents stamps.
100 cents = 1$
So 49 cents = $0.49
and 21 cents = $0.21
Hence equation be framed as;
Also Given:
number of .49-cents stamps was four less then three times the number of 21-cent stamps.
hence we can say that;
Now Substituting the value of equation 2 in equation 1 we get;
Now substituting the value of y in equation 2 we get;
Hence Kailee bought 26 of 49-cents stamps and 10 of 21-cents stamps.
