BNU1501 Second Assignment 1
Semester 1, 2020
Due Date: 20 February
Unique Number: 823796
Question 1
Round 10.34791 off to three decimal digits.
The fourth decimal digit, 9, will round up the third decimal digit, 7, to 8 to give
10.348
[Option 2]
Question 2
Round 10.99458 off to two decimal digits.
The third decimal digit, 4, will not affect the second decimal digit 9, so the answer
will be 10.99
[Option 3]
Question 3
Round 10.34791 off to one decimal digit.
The second decimal digit, 4, will not affect the first decimal digit, 3, so the answer
is 10.3
[Option 3]

Question 4
Suppose 𝑞 loaves of bread cost 𝑐 rands (R). Indicate an expression for the cost (in
rands, R) of three loaves of bread
20
Example: If 6 loaves cost 𝑅20 then one loaf costs rand.
6
𝑐
Application: if 𝑞 loaves cost 𝑐 rand then one loaf costs rand
𝑞
𝑐 𝑐 𝑐
Now if one loaf costs rand, then 3 loaves will cost 3 × = 3 rand
𝑞 𝑞 𝑞
[Option 1]
Question 5
If a certain number 𝑥 is increased by 7, it will be equal to twice that same number
decreased by 5. The correct equation/expression for the above sentence is:
𝑥 increased by 7 is 𝑥 + 7
Twice the same number (𝑥 ) 𝑖𝑠 2𝑥. 2𝑥 decreased by 5 is 2𝑥 − 5.
If both expressions are equal then:
𝑥 + 7 = 2𝑥 − 5
[Option 4]
Question 6
The correct formula/expression for a number which is five times as big as the
number obtained after 𝑥 has been decreased by three is:
When 𝑥 has been decreased by three, the result is 𝑥 − 3
Five times the above result is 5(𝑥 − 3)
