Lawrence has $50. He wants to buy some T-shirts that cost $12 each.

He also wants to have at least $10 left to buy lunch.

Which inequality shows the number of T-shirts, x, Lawrence can buy and still have at least $10 for lunch?

A. x≤3

B. x≥3

C. x≤4

D. x≥4

choice A) =<3

Step-by-step explanation:

x = number of shirts

50 -10 = x(12)

40 = 12x

x = 3 .33

d is correct

step-by-step explanation:

(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
