The value of y is 3 when x is 6.
Solution:
The given table is the amount of cheese in ounces and the cost price.
Let x represents the amount of cheese and y represents the cost price.
The formula which derived from the table is y = x ÷ 2.
That is
.
<u>To find the value of y when x is 6:</u>

Substitute x = 6 in the formula, we get

y = 3
Hence the value of y is 3 when x is 6.

The given series is

Where the first term, a , is 3.
And the difference is constant, that is

So the constant difference, d is 3.
Since the difference is constant, so the given series is arthmetic.
And for explicit rule, we use the formula of nth term, which is

Substituting the values of a and d, we will get

Recursive rule is used to tell us the relationship between previous and current term. And the required rule is

Answer:
Pedro pagó $448
Step-by-step explanation:
Sea P el precio inicial de un objeto.
Si aplicamos un descuento del X%, entonces el nuevo precio del objeto es:
NP = P*(1 - X%/100%)
y lo que estamos ahorrando es:
P - NP
En este caso, primero tenemos un descuento del 30%, entonces:
NP = P*(1 - 30%/100%) = P*(1 - 0.3)
Luego tenemos otro descuento, esta vez del 20%, entonces:
NP' = NP*(1 - 20%/100%) = P*(1 - 0.3)*(1 - 20%/100%) = P*(1 - 0.3)*(1 - 0.2)
Lo que Pedro ahorra es igual a $352
entonces:
P - NP' = $352
P - P*(1 - 0.3)*(1 - 0.2) = $352
P*(1 - (1 - 0.3)*(1 - 0.2)) = $352
P*(1 - 0.56) = $352
P = $352/(1 - 0.56) = $800
Esto significa que el precio original era $800.
Y lo que pedro pago esta dado por la ecuación:
NP' = P*(1 - 0.2)*(1 - 0.3) = $800*(1 - 0.2)*(1 - 0.3) = $448.
