So you would need to add:

500$ + 80$ + 175$ = 755$

Since John paid 900$ then you would subtract how much he is buying it for from how much Davis spent to fix it

900$ - 755$ = 145$ (on profit Davis earned)

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.
