Write the equation out: (total cost: 0.35C[per carton] + 75[delivery charge]) ≤ 500. Subtract 75 on both sides and it would be: 0.35C ≤ 425. Divide 0.35 on both sides and you'll get C ≤ 1214. Therefore, the maximum # of cartons that Elvira can buy is 1214 cartons of milk.

(Work is below)
First add the total of the vase and shipping-
Vase: $34.99
Shipping: $ 3.00
+__________
$37.99
Then calculate sales tax by multiplying $37.99 x 0.0825 -
Above Total: $37.99
Sales Tax Rate: $ 0.0825
x__________
$ 3.1341
You round down because ^ less than five (five or above you would round up)
Sales Tax: $3.13
Then you add the sales tax to the above total
Vase: $37.99
Shipping: $ 3.13
+__________
$41.12
No they are not equivalent
