Answer:

Step-by-step explanation:(a)

1.65p+1.36j=118.17 and p+j=79

We can say p=79-j and sub this value in first equation

1.65(79-j)+1.36j=118.17

130.35-1.65j+1.36j=118.17

-0.29=-12.18

j=42, p=79-j, p=79-42=37

(b)

1.65(37)=61.05 and 1.36(42)=57.12

Sanchez class earned more selling pies.

(c)

61.05-57.12=3.93

So Sanchez class made $3.93 more than Kelley class.
