A team t-shirt costs $3 per adult and $2 per child. On a certain day, the total number of adults (a) and children (c) who bought shirts was 100, and the total money collected was $275. Which of the following options represents the number of children and the number of adults who purchased team shirts that day, and the pair of equations that can be solved to find the numbers? (4 points) 75 children and 25 adults Equation 1: a + c = 100 Equation 2: 3a − 2c = 275 75 children and 25 adults Equation 1: a + c = 100 Equation 2: 3a + 2c = 275 25 children and 75 adults Equation 1: a + c = 100 Equation 2: 3a − 2c = 275 25 children and 75 adults Equation 1: a + c = 100 Equation 2: 3a + 2c = 275

peace out

jhonyy9:

so from these given details you know that a+c=100 and what result from there again ?

zackariahharriett:

oh sorry i was not thier i was away from my computer

zackariahharriett:

i dont know that was a random question i picked up

jhonyy9:

and that 3a +2c = 275 so using these two equations you need to solve them like a system and in this way will get the correct answer sure @Laylalyssa
