Answer:
13 2/9
Step-by-step explanation:
Cows eats=5 3/5 Hays everyday
Horses eats=1 5/6 as much as the cow
=1 5/6 of what the cow eat+5 3/5
=1 5/6 × 5 3/5 + 5 3/5
=11/6×28/6+28/6
= 308/36+28/6
=308+168/36
=476/36
=13 8/36
=13 2/9
Let h be the number of lemonade sold. If the vendor sold 86 items today and h of them are lemonade, then the rest are hot dogs, so he sold 86-h hot dogs.
When you add the number of sold lemonade and hot dogs, then you get 86 items in total:
h+(86-h)=86.
This equation is exactly the same as equation
(86-h)+h=86.
Moreover,
1. if a snack cart sells lemonade for $2, then he gets $2h for h sold lemonade;
2. if a snack cart sells hot dogs for $5, then he gets $5(86-h) for (86-h) sold hot dogs.
In total he gets $330, then
2h+5(86-h)=330.
Both these equations are true, but only first is among given options.
