Step-by-step explanation:
You have to find the unit price.
1750/7=250
Now, multiply the unit price by the desired amount.
250*12=3000
So, 12 calculators will cost 3,000.

You cannot "solve for f" here. However, you can find the zeros/roots of f. Set f = to 0. Then, one by one, set each of the factors = to 0 and solve for x:
x+1=0 results in x=-1; x-5=0 results in x=5, and so on.
Thus, the solutions of f(x)=0 are {-1, 5, -3, 4, 8}
You would do 3x60=180 since there is 60 minutes in each hour then dives 180 and 20 which gives you 9 batches of cookies. Hope this helps!

Answer: Rita and Tina's total weekly wages can be represented as 11r + 32 + 11t or 11( r + t ) + 32
Step-by-step explanation:
Since, For Rita,
Charges per hour = $ 11
Working time = r hours,
Overtime charges for a week = $ 32,
Thus, her weekly charges = 11 r + 32
Now, For Tina,
Charges per hour = $ 11
Working time = t hours,
Thus, her weekly charges = 11 t
Hence, the combined weekly wages of both Rita and Tina = 11 r + 32 + 11 t
= 11( r + t ) + 32
Which is the required expression.
