How to do this question I need to go to school on 1/9

ELEN [110]

$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

PS: celia should cut on chocolate. Not healthy for her :)

Shana took a test with 50 questions. She lost 2 points for each of the 5 questions she got wrong. She got all 3 extra credit que

jeka57 [31]

Answer:

She gained 5 points in overall

Step-by-step explanation:

Shana lost points for each wrong question = 2

So, She lost points for 5 wrong questions = $2 \times 5$

She lost points for 5 wrong questions = 10 points

Now, She gained points for each correct question = 5

So, She gained points for 3 correct questions = $5 \times 3$

She gained points for 3 correct questions =15

So, Overall gain = 15-10 = 5

She gained 5 points in overall

Hence the total number of points gained by her is 5 points
