Answer:
no
Step-by-step explanation:
you can't multiply any number by 2 to get 15
Step-by-step explanation:
y = -x² + 5
x = -2
y=-(-2)²+5
y= -4+5
y=1
Since he gets 10$ per shirt, his revenue is 10y if y represents the shirts sold as he adds 10$ with every purchase. His expenses start with the base cost of 1500, then he also has to pay 3 dollars for each shirt, so his expenses add up to 1500+3y. Since he wants to make as much as he spent, his revenue has to equal his expenses and 10y=1500+3y. Subtracting 3y from both sides, we get 7y=1500. Dividing both sides by 7, we get y=214.something=215 by rounding up
This would be 45.9
