Suzanne is landscaping her front yard. she made two trips to bring all the plants home. on the first trip she bought 8 flowers and 9 shrubs for $129. on the second trip she bought 12 flowers and 6 more shrubs for $126. if she bought the same kind of flower and shrub each time, what is the price, in dollars, of each shrub? (use only the digits 0-9 and a decimal point, if needed, to enter a number.)

$9

Step-by-step explanation:

Let price of flowers be f

and

let price of shrubs be s

On first trip, we can write:

8f + 9s = 129

On 2nd trip, we can write:

12f + 6s = 126

Since we need to find price of shrubs, we can solve the first equation for f and put it into 2nd equation and solve:

8f + 9s = 129

8f = 129 - 9s

f = (129 - 9s)/8

Now putting in 2nd, we solve for "s":

Hence

the price of each shrub is $9

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz
