Sandwiches = S
Water = W
S + W = 200
S +W -W = 200-W
S = 200-W
$3S + $0.75W = $318.75
$3(200-W) + $0.75W = $318.75
$600 - $3W + $0.75W = $318.75
$600 -$2.25W = $318.75
$600 - $600 - $2.25W = $318.75 - $600
- $2.25W = -$281.25
-$2.25W/-$2.25 = -$281.25/-$2.25
W = 125
S = 200-125
S = 75
Mikhael bought 75 sandwiches and 125 bottles of water
CHECK
$3S + $0.75W = $318.75
$3(75) + $0.75(125) = $318.75
$225 + $93.75 = $318.75
$318.75 = $318.75
Answer:

Answer: <em>You didn't provide the options so unable to know which option is the correct answer</em>
<u>Step-by-step explanation:</u>
x + 2 = 0 ⇒ x = -2
-2 | 4 -2 3

Step-by-step explanation:
Sammy's rate of eating pizza is ...
pizza/hour = (6/7)/(2/21) = (18/21)/(2/21) = 18/2 = 9
Sammy eats pizza at the rate of 9 pizzas in one hour.

<em>Comment on the question</em>
Sammy may only eat 6/7 of a pizza in an hour, because he is no longer hungry after eating that much.
