Urpi wants to buy towels online. There are two stores with the kind of towel she wants. The first store charges $20 per towel, and the delivery charge is $25. The following equation gives the total price (in dollars) of an order from the second store (including delivery) as a function of the number of towels: P=35+18nP=35+18n.

A) The first store
B) The second store
C) They both charged the same amount per towel.

2. Urpi needs 15 towels. Which store is cheaper for her?
A) The first store
B) The second store
C) Urpi's order costs the same at both stores.

1. The first store charges $20 per towel, according to the problem statement. According to the formula for the second store, the number of towels is multiplied by $18, so that store charges $18 per towel.

The first store charges $2 more per towel.

2. For an order of 15 towels, the first store would charge ...

$20 × 15 + 25 = $325

Answer:

1 A the first store.

2. B The second store.

Step-by-step explanation:

1. The store with the dearest towel is The First one ( $20 compared with $18).

2. The equation for the cost in the first store is P = 20n + 25.

The cost in the second store is given by P = 18n + 35.

For 15 towels first store charges:

20 * 15 + 25 = $325.

Second store charges:

18 * 15 + 35 = $305.
