X - the price of each pair of shoes;
3 x + 7.50 + 0.06 * 3 x = 126.81
3 x + 0.18 x + 7.50 = 126.81
3.18 x = 126.81 - 7.50
3.18 x = 119.31
x = 119.31 : 3.18
x = 37.52
Answer:
A ) $37.52
Since 6/1.5 is 4. It increased 400%.
5+3(q-4)=2(q+1)
mutiply the first bracket by 3
(3)(q)=3q
(3)(-4)=-12
mutiply the second bracket by 2
(2)(q)=2q
(2)(1)= 2
5+3q-12= 2q+2
5-12+3q= 2q+2
-7+3q= 2q+2
move 2q to the other side
sign changes from +2q to -2q
-7+3q-2q= 2q-2q+2
-7+3q-2q= 2
-7+q= 2
move -7 to the other side
sign changes from -7 to +7
-7+7+q= 2+7
q= 2+7
