Answer: £ 81.38
Step-by-step explanation:
Given: On Monday,
5 builders took hours ( i.e.
hours ) to build a wall.
On Tuesday, only 2 builders were available.
As workers are inversely proportional to the time if the job remains constant.
Inverse variation equation :
Let x be the time taken by 2 builders, then
So, 2 builders will take 8.75 hours.
Each paid £9.30 for each hour.
Then, each builder will be paid for the work completed on Tuesday = £9.30 x 8.75
≈ £ 81.38
Hence, each builder will be paid £ 81.38 for the work completed on Tuesday .
One possible solution for the system of inequalities is given as follows:
13 dimes and 2 nickels.
<h3>How to obtain the system of inequalities?</h3>The first step in obtaining the system of inequalities is identifying the variables, which are given as follows:
- Variable x: number of dimes that Tallulah has.
- Variable y: number of nickels that Tallulah has.
Tallulah has at most 18 coins, hence:
x + y ≤ 18.
A nickel is worth 5 cents = $0.05, while a dime is worth 10 cents = $0.1, and Tallulah has at least $1.20 combined, hence:
0.1x + 0.05y ≥ 1.20.
The solution is given by the shaded region on the image given at the end of the answer, and one possible solution is given as follows:
x = 13, y = 2.
Which means that she has 13 dimes and 2 nickels.
