Answer:
($x * 3) + ($1.25 * 2) = $5.05
$0.85 for 1 bag of chips
Step-by-step explanation:
Knowns: 3 bags of chips, 2 juices, cost of 1 juice, & total purchase amount
Unknown: cost of 1 bag of chips
So, (Cost of 1 bag of chips times number of bags of chips bought) + (cost of 1 juice times number of juices bought) = total cost
Now convert the words into numbers and variables (where x = cost of chips or unknown)...
(x * 3 bags of chips) + ($1.25 * 2 juices) = $5.05 total
simplify further...
(x * 3) + (1.25 * 2) = 5.05 (*this is your equation*)
solve further by multiplying 1.25 and 2, then subtracting that number from both sides to get the x by itself.
3x + (2.5) = 5.05
- 2.5 -2.5
Then, divide both sides by 3 to give the answer for x.
3x = 2.55
/3 /3
x = 0.85
Therefore, cost of one bag of chips is $0.85.
