Answer:
$20.30
Step-by-step explanation:
The usual price of the gift is $29.00
Marie will get 30% DISCOUNT on this price if she uses her coupon. So, the final price would be 30% less than $29.00
First, we need to find 30% of $29.00. Then we need to subtract that from original price (29).
Convert percentage to decimal first:
30% = 30/100 = 0.3
Now multiply this with 29 to get:
0.3 * 29 = $8.70
We subtract this from original price to get DISCOUNTED PRICE:
$29.00 - $8.70 = $20.30
Answer:
(-5.77, 6.46)
Step-by-step explanation:
15x + 9y = 45 ----------- i
9x + 8y = 12----------------ii
Multiply equation i by 9 the coefficient of x in equ ii
And equation ii by 15 the coefficient of x in equ I
9 x 15x + 9y = 45 ----------- i
15 x 9x + 8y = 12----------------ii
135x+81y = 405
135x+120y= 180
Subtract equation ii from I
135x-135x+81y-(+120y)= 405-180
-39y=225
y = 225/-39 = -5.77
Insert the value of y in equ i
15x + 9y = 45
15x+9(-5.77) = 45
15x-51.92=45
15x = 45+51.92
15x= 96.92
x = 96.92/15= 6.46
(x,y) = (-5.77, 6.46)
x = 6.92/15
