A snack cart sells lemonade for $2 and hot dogs for $5. The vendor sold 86 items today for a total of $330.

Katen [24]

Answer:

(86 – h) + h = 86

Step-by-step explanation:

$70+$260= $330

34 lemonade + 52 hot dogs = 86 items = $330

With 34 lemonade + 52 hotdogs h= 52

(86 – h) + h = 86 = 86-52+52=86
