Jess has 60 ounces of a metal alloy (mixture) that is 40% pure gold. (The other 60% is some other metal.) If Jess adds 10 more ounces of pure gold to the 60 ounces of alloy, he will then have 70 ounces of alloy. What will the percentage of gold in this alloy?

10 again

Step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
