Mark and melissa went to the garden center together to buy plants. mark bought six ferns and one azalea for $80. melissa bought five ferns and three azaleas for $84. how much was a single fern

Price of single fern is $12

Price of single azalea is $8

Step-by-step explanation:

Let's assume

price of each fern is x

price of each azalea is y

Mark bought six ferns and one azalea for $80

so, we got first equation as

Melissa bought five ferns and three azaleas for $84

so, we got second equation as

now, we can solve it

Firstly, we can solve for y from first equation and then plug that in second equation

now, we can plug that into second equation

now, we can solve for y

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
