## To find out how much one pear costs, you need to solve the system of equations:

Equation 1: 6p + 3a = 3.90 (where p represents the cost of one pear and a represents the cost of one apple)

Equation 2: 2p + 5a = 3.30

One way to solve this system of equations is by eliminating one variable. Let's eliminate the variable "a":

Multiply Equation 1 by 5 and Equation 2 by 3 to make the coefficients of "a" in each equation the same:

5(6p + 3a) = 5(3.90)

3(2p + 5a) = 3(3.30)

This simplifies to:

30p + 15a = 19.50

6p + 15a = 9.90

Now, subtract the second equation from the first equation to eliminate "a":

(30p + 15a) - (6p + 15a) = 19.50 - 9.90

24p = 9.60

Divide both sides of the equation by 24:

p = 9.60 / 24

p = 0.40

So, one pear costs $0.40.
