Hi!
The options regarding the inequalities are not listed, though we can still proceed to write the inequality.
From the problem statement you cannot spend more than $50
and you are charged admission fee of $6 flat
a ride cost $2.50 per ride
the number of rides is given as r
yet in all you must not go beyond your limit
Therefore the inequalities can be presented as
![6+2.5r\leq 50](https://tex.z-dn.net/?f=6%2B2.5r%5Cleq%2050)
Standard deviation of math scores is ≈1.1401
Standard deviation of English scores is ≈8.6197

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
