Answer:

The answer is below

Step-by-step explanation:

a) The number of pupils who scored more than 7 in a test = pupils who shored  8 + pupils who shored 9 + pupils who shored 10

The number of pupils who scored more than 7 in a test = 7 + 3 + 1 = 11 pupils

b) Total number of pupils = pupils who shored  0 + pupils who shored 1 + pupils who shored 2 + . . . + pupils who shored 9 + pupils who shored 10

Margaret [11]

Answer:

The answer is below

Step-by-step explanation:

a) Cost of hiring the bicycle for 14 days is:

Cost = 65 * 14 days + 44 = 954 riyals

b) The number of days the bicycle is hired is to be the same as the number of days the bicycle is to be hired. Let us assume that the bicycle and helmet is to be hired for x days, hence:

Cost of bicycle = 65 * x + 14 = 65x + 44

Cost of helmet = 12.5 * x = 12.5x

Total cost = 65x + 44 + 12.5x = 77.5x + 44

Since 750 riyals is available, hence:

750 = 77.5x + 44

77.5x = 706

x = 9.11

Therefore the maximum number of days is 11. The total cost for 11 days is:

Total cost = 77.5(9) + 44 = 741.5 riyals

Money not spent = 750 riyals - 741.5 riyals = 8.5 riyals
