Boar’s Head turkey costs $5.15 per pound. Mary needs to purchase 2.6 pounds for her family picnic. What is her total cost at the deli counter?

13.34

Step-by-step explanation:

5.15+5.15=10.30

+3.04=13.34

The north campus had 600 students (180 music majors)

The south campus had 400 students (280 music majors)

Step-by-step explanation:

x = number of students at the north campus before the merger

If the total of students for the two school is given as 1000, so:

(1000 - x) =  number of students at the south campus before the merger.

The equation for music major is:

0,3x + 0,7(1000-x) = 0,46(1000)

0,3x + 700 - 0,7x = 460

0,3x - 0,7x = 460 - 700

- 0,4x = -240

x = -240/-0,4

x = 600 > total number of students at the north campus

600*(0,3) = 180 music majors at the north

100 - 600 = 400 > total number of students at the south campus

400*(0,7) = 280>music majors at the south
