Answer: Cost of 1 soda = (Amount Juliana had- Cost of 3chips)/3
Step-by-step explanation: Cost of 3chips =$0.85×3= $2.55
Cost of 3 soda will be $6-$2.55
Cost of 1soda will be ($6-$2.55)/3
Cost of the toothbrush and the toothpaste together = $1.10
Let us assume the cost of the toothpaste = x
Then
The cost of the toothbrush is = (x + 1) dollar
Then we can write the equation as
x + x+ 1 = 1.10
2x + 1 = 1.10
2x = 1.10 - 1
2x = 0.10
x = 0.10/2
= .05 dollars
So the cost of the toothpaste is 0.05 dollars.<span>I hope
