Find the matrix aa of the linear transformation t(m)=[2041]m[2041]−1t(m)=[2401]m[24 01]−1 from u2×2u2×2 to u2×2u2×2, with respect to the standard basis for u2×2u2×2: {[1000],[0010],[0001]}{[1000],[0100 ],[0001]}.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
