Question

Winston earns $140.00 by selling 56 hot dogs at a concession stand at school. Using the same rate for the cost of one hot dog, how many more hot dogs would Winston need to sell to earn a total of $175.00 ?

Answer 1

Answer:

70 more hotdogs,

Step-by-step explanation:

Step 1: Lets find the cost of a single hotdog.

Let x be the rate of a single hotdog.

Winston earns $140 by selling 56 hotdogs.

So, to find the rate of one hotdog we will have to divide his earnings with number of hotdogs sold.

That is :

$\frac{140}{56}$ = 2.5

So now we know that each hotdog he sells costs $2.5

Step 2: Find how much more hotdogs he needs to sell.

To find that, first we need to know how much more he earn.

For that we'll subtract earnings from total earnings.

$175 - 140^$

= 30

Now as we know that a single hotdog costs $2.5, we can simply divide 30 with 2.5, that's:

$\frac{30}{2.5}$ = 14

∴ Winston needs to sell 14 more hotdogs to make his total earnings $175.
