chris buys a chocolate bar and a pack of gum for 1.75 if the chocolate bar costs .25 more than the pack of gum how much does the pack of gum costs?
cost of gum = x
cost of bar = x+.25
solve
x + x + .25 = 1.75
To find out how much the pack of gum costs, let's set up an equation based on the given information.
Let's assume the cost of the pack of gum is "x" dollars. Since the chocolate bar costs $0.25 more than the pack of gum, the cost of the chocolate bar can be represented as "x + $0.25".
As per the given information, Chris buys both the chocolate bar and the pack of gum for a total of $1.75. So we can set up the equation:
x + (x + $0.25) = $1.75
Now, let's solve this equation step by step to find the value of "x".
Combining like terms, we have:
2x + $0.25 = $1.75
Next, subtract $0.25 from both sides to isolate the variable:
2x = $1.75 - $0.25
Simplifying the right side, we get:
2x = $1.50
Finally, divide both sides by 2 to solve for "x":
x = $1.50 / 2
x = $0.75
Therefore, the pack of gum costs $0.75.
