Seriously: add the x's divide by 2, add the y's divide by 2, bob's your uncle. you have the midpoint.
96 → B
substitute w = 12 into the equation D = 3w + 60
D = (3 × 12 ) + 60 = 36 + 60 = 96
1/4 per day=4 days for one outfit so 4x18=72
The answer to your question is “D”
Btw you can use DESMOS for future questions like this
X is a variable, a variable you have to divide to cancel out
