Sales increased by only 12% last month. If the sales from the previous month were $152,850, what were last months sales

Mathematics
1 answer:
Tamiku [17]3 years ago
3 0

Answer:

\$171,192

Step-by-step explanation:

Remember that

100\%+12\%=112\%=112/100=1.12

we know that

The sales from the previous month were $152,850

This amount represent the 100%

so

Find out what were last months sales, multiply the sales from the previous month by the factor 1.12

\$152,850(1.12)=\$171,192

Kaitlin, Tony, and Austin sent a total of 103 text messages over their cell phones during the weekend. Austin sent 4 times as ma
emmainna [20.7K]

The number of messages Kaitlyn, Tony and Austin sent are 13, 18 and 72 messages respectively.

<h3>How to write and solve equation?</h3>

let

  • Number of messages Kaitlyn sent = x
  • Number of messages Tony sent = x + 5
  • Number of messages Austin sent = 4(x + 5)
  • Total messages = 103

103 = x + (x + 5) + 4(x + 5)

103 = x + x + 5 + 4x + 20

103 = 6x + 25

103 - 25 = 6x

78 = 6x

x = 78/6

x = 13

Number of messages each sent:

Number of messages Kaitlyn sent = x

= 13 messages

Number of messages Tony sent = x + 5

= 13 + 5

= 18 messages

Number of messages Austin sent = 4(x + 5)

= 4(13 + 5)

= 4(18)

= 72 messages

Given a polynomial f(x), if (x + 5) is a factor, what else must be true?
PolarNik [594]
Rule: If x-k is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem.

Using that rule, we can see that x+5 is really x-(-5) so k = -5. 

Therefore,

p(k) = 0
p(-5) = 0

so the answer is choice D.

A computer system is priced at $3200. A man buys
max2010maxim [7]

(i) Monthly installment is $21.53 approximately.

(ii) Total amount man has to pay is $3716.8

(iii) Extra money he had to pay for buying the computer on hire is $516.8

Given,

Initial price of the computer(p) = $3200

Down payment = $480

Time period = 2 yrs

rate percent = 9.5%

(i) Monthly installment = ?

monthly installment =(capital amount × interest rate)/time in months

down payment to be paid = 3200 ₋ 480

                                         = 2720

therefore, monthly payment = 2720 × 9.5 × 1/ 12

                                            = $21.53

(ii) Total amount man has to pay = ?

                                           = down payment ₊ remaining amount ₊                                                                                                                                                 (remaining amount × t × r)                                          

                                           = 480 ₊ 2720 ₊ 2720 × 9.5 × 2

                                           = $3716.8

(iii) If he buys the computer on hire then how much more he has to pay = ?

= total amount ₋ initial cost

= 3716.8 ₋ 3200

= $516.8

Hence the man has to pay $21.23 as a monthly installment, $3716.8 as a total cost of the computer system and $516.8 as an extra amount if he buys it on hire.
