Answer:
23 nickels and 16 dimes
Step-by-step explanation:
16 dimes = 1.60
23 nickels = 1.15
1.60 + 1.15 = 2.75
x=quantity of days
$38.00+$2.75x=$31.75+$4.00x
We can cancel all $...
38.00+2.75x=31.75+4.00x
It is just as important to cancel symbols as numbers.
Next, we isolate x.
We will begin by subtracting 31.75 from both sides...
-31.75+38.00+2.75x=4.00x
6.25+2.75x=4.00x
Then, we will divide both sides by 4.00...
(6.25/4.00)+((2.75x)/4.00)=(4.00x)/4.00
1.56+0.69x=x
Then, we will subtract 0.69x from both sides...
-0.69x+1.56+0.69x=x-0.69x
1.56=0.31x
Then, we will divide both sides by 0.31...
1.56/0.31=(0.31x)/0.31
5=x
Let's check our numbers...
The original equation was...
$38.00+$2.75x=$31.75+$4.00x
38.00+2.75(5)=31.75+4.00(5)
38.00+13.75=31.75+20.00
51.75=51.75
