1 answer:
Flauer [41]3 years ago
6 0

Answer:

A)15x+30=weekly income

B)8 hours

Step-by-step explanation:

15x+30= weekly income

The 15 multiplies because it says per hour

The 30 is constant because she only earns it once (per week)

15x+30=150

minus 30 from both sides

15x=120

divide by 15

x=8

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.

Answer:

6x-4y=24

Step-by-step explanation:

From the graph, there are two intersections to be found one at (4,0) and another at (0,-6)

Now,

slope,m= y1-y2/x1-x2

=0+6/4-0

=3/2

The equation of the straight line passingt through the point (4,0) is

y-y1=m(x-x1)

or, y-0=3/2 (x-4)

or, 2y=3x-12

or, 3x-2y=12

or, 2(3x-2y)=2(12) [Multiplying both sides by 2]

or, 6x-4y=24
