First, let's write an equation for the situation.
Jim's weight is 30 pounds less than Tom's, so his weight is:
n - 30
If Tom's and Jim's weights add to 210:
n + (n - 30) = 210
Solve for n:
2n - 30 = 210
2n = 240
n = 120
Tom weighs 120 pounds.
So to compare boxes, you want to convert both to price per ounce unit.
So for smaller box, we have ratio $2.89 / 17 ounces which can be reduced to $0.17 per ounce. You just divide 2.89 by 17.
Now for larger box, we have ratio $3.29 / 24 ounces which can be reduced to approximately $0.14 per ounce. 0.137083333... to be exactly.
Larger box has smaller ratio compared to smaller box therefore larger box the is better buy.
The difference per ounce is 0.17 - 0.137083333... = 0.03291666... so that's 3.3 cents cheaper per ounce.
Final answer: <span>The larger box is the better buy because it is approximately 3.3 cents cheaper per ounce.</span>

Step-by-step explanation:
Answer:
3x + 2
Step-by-step explanation:
x = 1x but leaving the x alone equals the exact thing.
If there are x + x + x, this means 3x since it is also
1x + 1x + 1x.
This is another expression for 3x + 2.
This is the correct graph.
1. Locate the y-intercept on the graph and plot the point.
2. From this point, use the slope to find a second point and plot it.
3. Draw the line that connects the two points.
