Answer:
Mary is 35.
Step-by-step explanation:
An equation would be <em>5j + j = 42.</em>
I used substitution by plugging in 7:
5(7) + 7 = 42
35 + 7 = 42

35
M=5J
J=M/5
42=6J
42/6=7
Jullian is 7
7x5=35
Mary is 35
35+7=42
The cost of a single shot is
.78 +.52 +.96 = 2.26
they charge 25 a shot
25 - 2.26 = 22.74
there is a profit of 22.74 per shot
22.74 * 167 =3797.58
They make $3797.58
