a delivery truck carries 8 pallets with 20 boxes on each pallet. the driver unloads 53 boxes at the first stop. how many boxes remain on the truck? write an equation and solve.

a movie theater has 9 rows with 14 seats in each row. during a showing 37 seats are empty. how many people are watching the movie? write an equation and solve.

a baker makes 63 cookies and boxes them into packs of 7. he sells 4 packs. how many cookies remain? write an equation and solve.

Explanation:

Problema 1: Leo's páginas

Step1: Calcular páginas de 4 días

$15 \times 4 = 60$

Step2: Sumar páginas del día 5

$60 + (15 + 10) = 60 + 25$

Step3: Total de páginas

$60 + 25 = 85$

Problema 2: Cajas del camión

Step1: Calcular cajas iniciales

$8 \times 20 = 160$

Step2: Restar cajas descargadas

$160 - 53 = 107$

Problema 3: Personas en el cine

Step1: Calcular asientos totales

$9 \times 14 = 126$

Step2: Restar asientos vacíos

$126 - 37 = 89$

Problema 4: Galletas restantes

Step1: Calcular galletas vendidas

$4 \times 7 = 28$

Step2: Restar galletas vendidas

$63 - 28 = 35$

Answer:

1. Ecuación: $15 \times 4 + (15 + 10) = P$, Total de páginas: 85
2. Ecuación: $8 \times 20 - 53 = C$, Cajas restantes: 107
3. Ecuación: $9 \times 14 - 37 = P$, Personas en el cine: 89
4. Ecuación: $63 - (4 \times 7) = G$, Galletas restantes: 35
