Correct answer gets brainliest. If johnny had 3,780 fake dollars from doing chores and his mom told him that he can buy something from Amazon for every 500 fake dollars is 10 real dollars. he wanted to buy something that is 68 dollars how much fake money does he need.

he needs 4,000 fake dollars

Step-by-step explanation:

right now he has enough to buy something for $60 so he needs another 220 fake dollars to have enough for a $68 item

3400

Step-by-step explanation:

3780/500=7.56

7.56x10=75.6

75.6-68=7.6

7.6/10=0.76

0.76x500=380

3780-380=3400

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.
