Given the statement:
A euro is equal to 1.2 American dollars.
Estimate the number of American dollars to 25 euros.
Solution:
In order to estimate, we must first represent the given,
Euro = 1.2 x
x = American dollars
Substitute the value of 25 euros to the formula and solve for x in order to determine the value in American currency.
25 = 1.2x
Divide both sides by 1.2 in order to determine the value of x.
25/1.2 = 1.2x/1.2
x = 20.833..
Final answer:
=$20.83
