Answer:
$3850
Step-by-step explanation:
It is given that,
A girl scout troop makes $1100 in two weekends of selling cookies.
2 weekend = $1100
1 weekend = $550
For 7 weekend, we will multiply $550 by 7 as follows :
7 weekend = $550 × 7
= $3850
So, for 7 weekend she will need $3850.
Answer: it will take a combined rate of 2.67 hours
Step-by-step explanation:
Father can do the job on the farm in 6 hours. This means that the father's unit rate of working will be 1/6
The older son can do it in 8 hours. This means that the older son's rate of working will be 1/8
The younger son can do same job in 12 hours. This means that the younger son's working rate is 1/12
When they work together, they will be working simultaneously. It means that their unit rates are additive. The combined unit rates will be
1/6 + 1/8 + 1/12 = (20 + 15 + 10)/120
45/120
Assuming it takes t hours for them to complete the work while doing it together. Their combined unit rate will be 1/t
45/120 = 1/t
45t = 120
t = 120/45 = 2.67 hours
