Answer:

$7.55

Step-by-step explanation:

We can solve this by using a system of equations. The equations would be set up like this:

$2c + p = 3.15\\3c + 2p = 5.35\\$

Let's isolate a variable in the first equation:

$p = -2c + 3.15$

Now we can plug this in to the second equation:

$3c + 2(-2c + 3.15) = 5.35\\3c - 4c + 6.3 = 5.35\\-c + 6.3 = 5.35 \\-c = -.95\\c = .95$

Now that we have found c we can find p by plugging c in to an equation

$2(.95) + p = 3.15\\1.9 + p = 3.15\\p = 1.25$

We have found both variables now we can use the following equation to answer the question:

$4c + 3p = ?\\4(.95) + 3(1.25) = ?\\3.8+3.75 = 7.55$

Therefore, the price in dollars of 4 cucumbers and 3 peppers is $7.55.
