There were 117 more customers who ordered onion rings than french fries.

There were 351 customers who ordered french fries.

There were 195 fewer customers who ordered french fries than onion rings.

Answer 1

Answer:

There were 117 more customers who ordered onion rings than french fries.

Step-by-step explanation:

We know that:

3 out of every 5 customers ordered onion rings

Then the ratio of customers that ordered onion rings is:

(3/5) = 0.6

2 out of every 5 customers ordered fries.

Then the ratio is:

(2/5) = 0.4

Now, we know that at the end of the day, she had 585 orders.

Then we can estimate that:

The total number of customers that ordered onion rings is equal to the ratio of customers that ordered onion rings times the total number of customers, this is:

N = 0.6*585 = 351

And for fries, we have:

M = 0.4*585 = 234.

The difference is:

N - M = 351 - 234 = 117

Then the correct statement is:

There were 117 more customers who ordered onion rings than french fries.
