A, C, E (NOT B or D)

Responder:
$ 750
Explicación paso a paso:
Dado que :
Descuento en todos los artículos = 20%
Descuento adicional dado = 15%
Monto final pagado por la camisa = $ 510
Precio de la camiseta sin descuento:
Sea el precio inicial de la camisa = x
Primer descuento obtenido = 20%
Precio pagado después de un descuento adicional del 15%
Primer descuento:
(1 - 0,20) * x = 0,8x
Segundo descuento:
(1 - 0,15) * 0,8x = 510
0,85 * 0,8x = 510
0,68x = 510
x = 510 / 0,68
x = $ 750

Answer:
3 3/4 yards of material
Step-by-step explanation:
Mandy was making 6 pillows, to give to her family. She needed 5/8 of a yard of material for each pillow. How many yards of material does she need?
From the above question:
1 pillow = 5/8 yard
6 pillows = x yards
Cross Multiply
1 pillow × x yards = 6 pillows × 5/8 yards
x yards = 6 pillows × 5/8 yards/1 pillow
x yards = 3 3/4 yards of material
Therefore, she needs 3 3/4 yards of material to make 6 pillows.
