1 Lunch 29.1

2 Lunch 5.8

3 Lunch 31.25

2 Lunch total 32.15

Tuesday total 53.15

total 139.85

Step-by-step explanation:

21.45-50.55=29.1

26.35-20.55=5.8

25.90-57.15=31.25

21.45+5.8+25.90=53.15

53.15+86.70=139.85

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
