Okay. You can decompose 749 with these ways:
700 + 40 + 9
or
500 + 200 + 40 + 9
8x - amount of boys
7x- amount of girls
8x + 7x = 195
15x= 195 ( divide by 15)
x= 13
8x = 8 x 13 = 104
7x = 7 x 13= 91
there are 104 boys, and 91 girls.
Answer: She needs to bowl 120 or more on her next game.
Step-by-step explanation:
We know that:
Profit = Revenue - Cost
Let us say x number of candies are made per week.
Finding Cost per week:
Cost of making 1 bar = 0.15
Cost of making x bars = 0.15x
Fixed rate of making candies per week = 600
Total cost of making x candies per week = 600 + 0.15x
Now let us find Revenue:
Selling price of each bar = 1.50
Selling price of x bars = 1.50x
Now we have to find profit,
Profit = Revenue - Cost
In order to have profit Revenue - Cost >0
So plugging values of revenue and cost to get number of candies,




x>444.44
Rounding off
x>444
Answer: The company must sell greater than 444 candies in order to make profit.
Answer:
6⅔ minutes
Or, 6 minutes 40 seconds
Step-by-step explanation:
X/10 + X/20 = X/T
(2X+X)/20 = X/T
3X/20 = X/T
3/20 = 1/T
T = 20/3
T = 6⅔ mins
