Let the cost of the soft drink = C then the price of the sandwich was 3.5 times as much = 3.5C
And
C + 3.5C = Total Cost
C + 3.5C = 9
4.5C = 9 divide both sides by 4.5
C = 9/4.5 = $2.00 for the soft drink
And 3.5C = 3.5(2.00) = $7.00 cost of the sandwich
Answer:
3/4
Step-by-step explanation:
divided by 3 to get the answer.
First we'll substitute
with 

Then we can separate this.

Then we'll solve this.



Then we'll plug in to find the extraneous solutions (if any)

<span>[3 - (4 + 32 * 8) ÷ 4]
=</span>[3 - (4 + 4) ÷ 4]
= 3 - 8 ÷ 4
= 3 - 2
= 1
