Answer:
Amount of Type B coffee used = 99 pounds
Step-by-step explanation:
Let the amount of type A taken be x pounds and type B taken be y pounds.
But we know that the total amount of coffee used = 177 pounds.
Type A coffee costs $5.70 per pound and type B coffee costs $4.10 per pound.
The total cost for the blend = $850.50.
We have to find the pounds of type B coffee used.
Equating the total costs,
5.70x + 4.10y = 850.50
x + y = 177
Substitute x = 177 - y in the first equation.
5.70 + 4.10y = 850.50
158.40 = 1.60 y
y = = 99
Amount of Type B coffee used = 99 pounds
It took him 1 hour and 30 mins .
He needs to go 15 miles. It takes him 1 hour to get 10 miles. After 1 hour has passed he still needs 5 more miles to go. 5 miles is half of 10 so half of 1 hour is 30 mins. 1 hour + 30 mins is 1 hour and 30 mins. (It took him 1 hour 30 mins)

Answer:
7
Step-by-step explanation:
Let x be the amount of cups he ordered per month.
There are 12 months in a year.
Therefore, 12 times x plus 16 (the amount he has left) must equal to 100. Thus:
Subtract 16 from both sides:
Divide both sides by 12:
Therefore, Len ordered 7 cups of tea per month.
