$7.9 cost of one pack
10 packs cost is $79
She pays $29 + Voucher

From the total $79 we substract the $29 she paid with cash or card.

79-29=50

So the value of the voucher is $50

1 pack = $7.90

10 packs = $7.90 x 10 = $79

Celia pays $29 plus a voucher to equal $79.

29 + (voucher) = 79

(voucher) = 50 <em>subtracted 29 from both sides</em>

Answer: $50

From this we can read the general solution, x = ⎡. ⎢. ⎢. ⎢. ⎢. ⎣ ... two vectors are clearly not multiples of one another, they also give a basis. So a basis ... 4.4.14 The set B = {1 − t2,t − t2,2 − 2t + t2} is a basis for P2.
