Step-by-step explanation:
Start by creating expressions
t= A tray of tomato plants
3t = $16.47
Solve the equation above
3t/3= 16.47/3
t= 5.49
A tray of tomato plants costs $5.47
Now create the ratios
b= A tray of basil plants
t:b = 3:2
Substitute t
5.49:b = 3:2
Rewrite as fractions
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
Cross multiply
5.49(2) = 3(b)
10.98 = 3b
10.98/3 = 3b/3
3.66 = b
A tray of basil plants costs $3.66
In total she bought 3 trays of tomato plants, which cost $16.47, and 10 trays of basil plants
T0 find out the cost of the 10 basil plants, multiply 3.66 by 10
3.66 × 10 = 36.6
She bought 10 trays of basil plants for $36.60 and 3 trays of tomato plants for $16.47
Add the 2 values together
36.60+16.47 = 53.07
$53.07 is the total
I hope this helps!!!
Answer:
1
Step-by-step explanation:
|z-6|= -(z-6) since z<5
|z-5|= -(z-5)
|z-6| - |z-5|= -(z-6)+(z-5)
= 1
The sales tax is 18 ×
![\frac{7}{100}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B100%7D%20)
, which is 1.26
The DVD + sales tax is:
18 + 1.26
= 19.26
The total price will be $19.26. She has $20, so she will have enough money
Answer:

k=9 I think..... I'm not completely sure but I think that's how it is
The persons above me is correct
