Answer:
A. (0,445)
D.(118,209)
E.(172,101)
Step-by-step explanation:
The equation that we have in this problem is:
where
d is the number of dimes
n is the number of nickels
$22.25 is the total amount of money collected by Diego in the jar.
In order to find which pairs of values can be solutions to the equation, we just need to substitute each pair (d,n) into the left term on the equation, and check if the result is 22.25. Let's do it:
A. (0,445)
--> YES
B. (0.50,435)
--> NO
C. (233,21)
--> NO
D.(118,209)
--> YES
E.(172,101)
--> YES
So the correct pairs are:
A. (0,445)
D.(118,209)
E.(172,101)
