Answer:
B 4
Step-by-step explanation:
She bought 2 jackets
Jackets = 2*49 = 98
She bought 3 sweaters
Sweaters = 3 * 25 = 75
The costs for the jackets and sweaters is 98+75 =173
She spent a total of 185
185-173 = 12
She spent 12 dollars on socks
Socks are 3 dollars each
12/3 = 4
She bought 4 pairs of socks
(3.10/3.35)-1*-1=0.07462686567
So the percantage decrease to the nearest tenth is 7.4%
3.35 x 0.07462686567= .25
^
The price difference which is 25cents
From the first equation we get y = 2x. Subbing this into the second equation, we get:
x^2 (2x)^2
------ - --------- = 1, or
25 49
x^2 4x^2
------ - --------- = 1
25 49
