@TheSmartOne

Answer 3

lets say x is the plastic bowl and y is the steel bowl.

Answer 4

so 6x+10.50y=136.50

Answer 5

We know that x=7

Answer 6

6x7=42 ----> 42+10.50y=136.50
What's Y?

Answer 7

subtract 42 on both sides.
So 10.50y=94.5
Divide by 10.5 on both sides
y=9

Answer 8

Answer 9

OK so...
6x7=42
42+10.50y=136.50
10.50x9=94.50
42+94.50=136.50
He bought 63 bowls?

Answer 12

How many stainless steel bowls did Malcolm buy?

Answer 13

look back at TheSmartOne's post where x and y are defined

Answer 14

what are x and y?

Answer 15

9 and 7. Do I multiply them?

Answer 16

x = 9 means what?

Answer 17

9 is one of the types of bowls?

Answer 18

yes go back and see how TheSmartOne defined x and y

Answer 19

X as the Plastic Bowls = 7
Y as the Steel Bowls = 9

Answer 20

so because y = 9, there are 9 steel bowls

Answer 21

Oh. I thought it wanted to know how many bowls there were together. :) I see. I already knew that. The answer would be 9, right?

Answer 22

nope, they're just asking about the steel bowls
