So, we would obviously add these two numbers together.
$1.10 + $1.25 = $2.35
$2.35 is your answer.
Answer:
I mean c and d but you wrote this weirdly
Answer:
The cost of each drink is $6.58
Step-by-step explanation:
<u><em>The correct question is</em></u>
Someone buys 4 drinks and 2 popcorn and spent a total of $32.50. Each drink is $3.50 more than a popcorn. How much does each drink cost?
Let
x ----> the cost of each drink
y ----> the cost of each popcorn
so
----> equation A
isolate the variable y
----> equation B
Solve the system by substitution
substitute equation B in equation A
solve for x
therefore
The cost of each drink is $6.58
Answer:
I think it's all of them :)
So, 4 quarts of 10% antifreeze consists of .1 * 4 = .4 quarts of antifreeze.
x quarts of pure antifreeze consists of x quarts of antifreeze.
Mixing them together, the proportion of the solution that is antifreeze is given by
(.4 + q)/(4 + q).
We want to solve for a solution consisting of 50% antifreeze,
(.4 + q)/(4 + q) = .5 -> q = 3.2.
So, 3.2 quarts of pure antifreeze is required.
