Ответ:
Downloading one music for member = $0.99
Downloading two pieces of music for member = 2 × 0.99
Downloading three pieces of music for member = 3 × 0.99
Downloading 'x' pieces of music for member = x × 0.99 = 0.99x
Plus the membership club fee of $48
The expression of the total amount of fee charged to a member for 'x' pieces of music downloaded = $48 + 0.99x
Let 'x' be the number of pieces of music downloaded by a non-member.
The total cost of downloading 'x' pieces of music is 1.29x
Cost downloading as member = Cost downloading as non-member
48 + 0.99x = 1.29x
48 = 1.29x - 0.99x
48 = 0.3x

The equation which relates the point at which the cost as member and non-member equals is 48 + 0.99n = 1.29n
Let :
number of songs downloaded = nCost as a Member :
Membership fee = $48Cost per download = $0.99Total cost = 48 + 0.99nCost as a non-member :
Cost per download = $1.29Total cost = 1.29nThe point at which total cost expended as a member equals that of a non-member can be expressed thus :
Total cost as member = Total cost as non-member48 + 0.99n = 1.29nTherefore, the required expression is 48 + 0.99n = 1.29n
