Define a variable, then write and solve an inequality: alex and his mother spent at least $130 while shopping for new clothes. alex spent $52. how much money did his mother spend?

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
