The farmer and daughter working together would take 6 days to plant the field
<h3><u>Solution:</u></h3>
Time taken by farmer to plant a field is 10 days
Time taken by his daughter to plant a field is 15 days
<em><u>Now lets find L.C.M of 10 and 15</u></em>
List all prime factors for each number.
Prime factorization of 10 = 2 x 5
Prime factorization of 15 = 3 x 5
For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.
The new superset list is
2, 3, 5
Multiply these factors together to find the LCM.
LCM = 2 x 3 x 5 = 30
Thus L.C.M of 10 and 15 is 30
<em><u>When both of them work together:</u></em>
Hence, both of them can complete the work in 6 days

Step-by-step explanation:
Answer:
4
Step-by-step explanation:
The amount spent for 6 meals = $48
The coupon for a regular price of each meal is =$8
Leting p= regular price of each meal then an equation for regular price of each meal will be;
For 6 meals = $48
For 1 meal = $48/6 = $8
Letting p to be the regular price of a meal
This will be;
6 {p-$8} = $48 -----this means p minus the off coupon price multiplied by total number of meals, 6, should give $48 as the paid total amount.
Solving the equation will have;
6p - $48 = $48
6p = $48 + $48
