Answer:
The statement is not reasonable.
Step-by-step explanation:
Josefina gave away 130% of her stamp collection.
We cannot give more than what we have.
lets understand it mathematically.
suppose i have x stamp.
according to question, i have to give 130% of my stamp collection
130% of x = 130/100 x = 1.3x
so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.
maximum i can give is x stamp.
x stamp in percentage of my total stamp collection which is also x will be
= x/x*100 = 100%
Thus, maximum one can give is 100% of what he has.
Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.
Answer:
Step-by-step explanation:
a) Let the cost of a Pizza = $ x
Cost of three pizza's = 3 *x = 3x
cost of 3 pizza + cost of a salad = $ 20.7
3x + 3 = 20.7
b) 3x + 3 = 20. 7 {Subtract 3 from both sides}
3x = 20.7 - 3
3x = 17.7 {Divide both sides by 3}
x = 17.7/3
x = 5.9
Cost of one pizza = $ 5.9
