Answer:

A

Step-by-step explanation:

The consecutive values of a_{n} have a common difference d, that is

d = 8 - 3 = 13 - 8 = 18 - 13 = 23 - 18 = 5

This indicates that the sequence is arithmetic.

The recursive formula allows the next term in the sequence to be found from the previous term by adding 5, thus

a_{n} = a_{n-1} + 5 → A

sattari [20]

Answer: the total number of coupon books sold is 20.

Step-by-step explanation:

Let x represent the number of coupon books that Mario sold.

Let y represent the number of coupon books that Luigi sold.

Apparently, Mario is a much better salesperson, because he sold 4 times as many coupon books as Luigi. This is expressed as

x = 4y

If Luigi sold 12 fewer coupon books than Mario, the expression would be

x = y + 12 - - - - - - - - - - -- -1

Substituting x = 4y into equation 1, it becomes

4y = y + 12

4y - y = 12

3y = 12

y = 12/3

y = 4

x = 4y = 4 × 4

x = 16

The total number of coupon books that the two boys sold is

4 + 16 = 20

A patient drinks 5 12ounce cups of coffee daily. The doctor recommends cutting back 60%, how many ounces of coffee can the patie
maksim [4K]

The patient is recommended to take 24 ounces of coffee per day.

<u>Step-by-step explanation:</u>

Patient normal intake of coffee daily = 5 times 12 ounces

                                                          = 5 × 12 = 60 ounces

Doctor recommends to cut off 60 % of the normal intake of coffee.

And advised to take only 40 % of the daily intake of coffee.

So 60 % of 60 ounces can be calculated as,

$\frac{60 \times 60}{100}= 36 ounces

40 % of 60 ounces is 24 ounces.

So 60 - 36 = 24 ounces of coffee per day
