Answer:
10 incorrect answers
Step-by-step explanation:
Correct answer = +3
Incorrect answer = - 1
Mark scored = 20
Number of correct answers = 10
Let:
Incorrect answers = y
Hence, we can fashion out the expression for total score :
(Number of correct answers * score per Correct answer + number of incorrect * score per incorrect) = total score
(10 * 3) + (y * - 1) = 20
30 - y = 20
-y = 20 - 30
-y = - 10
y = 10

Answer:
Step-by-step explanation:
Mr Thomas earns 18.80 per hour for the first 40 hours of work in a week. This means that the total amount that he earned in the first
40 hours of work would be
40 × 18.8 = $752
He earns 1 and a half times and that amount per hour for each hour he works over 40 hours in a week. This amount per hour would be
1.5 × 18.8 = $28.2
Last week, Mr Thomas worked 45.5 hours. The extra hours that he worked is 45.5 - 40 = 5.5 hours.
Amount earned for 5.5 hours is
5.5 × 28.2 = $155.1
Total amount that Mr Thomas earned is
752 + 155.1 = $907.1
