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
The equation is a + 9 = 15
Step-by-step explanation:
Let the number be 'a'
Given that,
A number plus 9 is 15
So,
a + 9 =15
a = 15 - 9
a = 6
The equation needed is,
a + 9 = 15
