Answer:
n = 6.30
Step-by-step explanation:
-5n+2.75 -2.75= -28.75 - 2.75
-5n =-31.50
divide both sides by -5
-5n/-5 = -31.50/ -5
the -5's cancel out . . .n = 6.30

Answer:
$40
Step-by-step explanation:
x is the original price of the gift
(10% of x) is the value of the discount
(10% of x) = 10/100 . x = 0.1 x
0.1 x is the value of the discount
x - (10% of x) is what was paid, after the discount
x - 0.1 x = 0.9 x
0.9 x is what was paid
4 children paid $9/each
4 times $9 = $36
$36 is the total amount that was paid by the children
$36 = 0.9 x
$36 / 0.9 = x
x = $36 / 0.9 = 360 / 9
x = 40
