-3^2= -(3)^2
The exponent of 2 only applies to the number 3. -(3)^2 should equal -9. This is true because according to the order of operations, exponents should be evaluated before multiplication. The negative sign here represents -1* 3^2.
If you want to find -3 to the power of 2 it must be written (-3)^2.

Step-by-step explanation:
To solve this, we either find the total cos5 of buying 40 bouquets at $2.50 or find the cost of one bouquet at $120.
Cost of one in pack of 40 at $120.
120 divided by 40 = $ 3
Now, we can see that $3>$2.50
This means that Kendra is wrong to buy the bouquet pack of 40 for $120
Hope this helps.
Good Luck
