Answer:153
Step-by-step explanation:
From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.
If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:
= 3/25 × 1280
= 153.6
There will be 153 students expected
Ok set the necklace as X and the bracelet as Y
X+Y=192
X=3Y
Plug in 3Y for X in the first equation
4y=192
Y=48$
Plug that into your second equation
X=3(48)
X=144$
