Liza earns $3200 a month. She spends 3/8 of her salary every month. She gives her parents 2/5 of the reminder and saves the rest. How much money does she save every month

$2480

Step-by-step explanation:

First, find a common denominator of the  fractions

15/40  and  16/40

then add them to find the total spending each month

12/40 + 16/40

=31/40

= 0.775

then do 0.775 (her spending) multiplied by 3200(salary)

0.775 x 3200

=$2480

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
