Go to mathway and type in the problem and it shows you the answer.
Let's named variables as M,J and R
The equation is M+J+R=74
We will represent M with J => M=J+6 and R=2J
when we replace in the equation we get
J+6+J+2J=74 => 4J=74-6 => 4J=68 => J=68/4 = 17
J=17 => M=6+17 => M=23 and R=2* 17 => R=34
Final answer is
Juan served 17 orders
Melissa served 23 orders and
Rafael served 34 orders
Good luck!!!!
To find the answer you will write and equation in terms of the cost of a bag of chips.
3(cost of milk) + 4 (cost of water) + 8 (cost of bag of chips) = $21.30
3 (2c +1.60) + 4 (2c) + 8 (c) = $21.30 ; Simplify
6c + 4.80 + 8c + 8c = 21.30
22c + 4.80 = 21.30
- 4.80 -4.80
<u>22c </u> = <u>$16.50</u>
22 22
c = 0.75
The chips cost $0.75 each.
The milk costs (2 x $0.75 + $1.60) $3.10 each.
The water costs (2 x $0.75) $1.50 each.
Answer:
$28
