Patty spent 3 1/2 times as much as Sandy. if sandy spent $20.50, how much did patty spend

12.6$

Step-by-step explanation:

1$ - 20$ = 19$ / 3 = 6.3$

6.3$ x 2 = 12.6$

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
