Leo had $91, which is 7 times as much money as Alison had. How much

NARA [144]

Answer:

$7x=91$

$13.

Step-by-step explanation:

Let x represent money that Alison has.

We have been given that Leo has 7 times as much money as Alison had. So the amount of money that Leo has, would be $7x$ .

We are also told that Leo had $91, so we will equate $7x$ with 91 and solve for x as:

$7x=91$

To solve for x, we will divide both sides by 7:

$\frac{7x}{7}=\frac{91}{7}$

$x=13$

Therefore, Alison has $13.
