Given:

a.) The first store sells between 100 and 200 tires on Friday and the same amount on Saturday.

b.) The other store sells between 200 and 450 tires on Friday and the same amount on Saturday,

Since we are asked about the possible range of the total number of tires sold at both stores on Friday and Saturday, computing the inequality will be:


\text{ Minimum number of tires sold (Store 1 and 1) }\leq\text{ x }\leq\text{ Minimum number of tires sold (Store 1 and 2)}

In the first store:

Friday:

Minimum number of tires sold = 100

Maximum number of tires sols = 200

Saturday:

Minimum number of tires sold = 100

Maximum number of tires sols = 200

In the second store:

Friday:

Minimum number of tires sold = 200

Maximum number of tires sols = 450

Saturday:

Minimum number of tires sold = 200

Maximum number of tires sols = 450

We get,


(100\text{ + 200) + (100 + 200) }\leq\text{ x }\leq\text{ (200 + 450) + (200 + 450)}
300+300\text{ }\leq\text{ x }\leq\text{ 6}50\text{ + 650}
\text{ 600 }\leq\text{ x }\leq\text{ 130}0

Therefore, the answer is 600 tires ≤ x ≤ 1300 tires
