A television with a price of
$300\$300
$300
dollar sign, 300
is to be purchased with an initial payment of
$60\$6
$60
dollar sign, 60
and weekly payments of
$30\$30
$30
dollar sign, 30
. Which of the following equations can be used to find the number of weekly payments,
ww
w
w
, required to complete the purchase, assuming there are no taxes or fees?
Choose 1

(Choice A)
A

300=30w−60300 = 30w - 60
300=30w−60
300, equals, 30, w, minus, 60

(Choice B)
B

300=30w300 = 30w
300=30w
300, equals, 30, w

(Choice C)
C

300=30w+60300 = 30w + 60
3

C. 300=60+30w

Step-by-step explanation:

Given:

Let weekly payments be w:

The initial payment plus the weekly installments should be equivalent to the television price:

The number of weekly payments is 8 weeks and the equation used to solve it is 300=60+30w

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
