Lunna [17]

Answer:

29 pounds of type A coffee was used

Step-by-step explanation:

David's shop makes a blend that is a mixture of 2 coffee

Type A costs $4.10

Type B costs $5.25

Let a represent the number of pounds of type A coffee used

Since this month's blend used twice as many pound of type B coffee as type A

a + 2a

The total cost is $423.40

Therefore the amount of pounds of type A coffee used can be calculated as follows

4.10a + 5.25(2a)= 423.40

4.10a + 10.5a= 423.40

14.6a= 423.40

a= 423.40/14.6

a= 29

Hence 29 pounds of type A coffee was used

PLS HELP ME, PLS THIS IS DUE FIRST CORRECT ANSWER GETS BRAINLIEST​
shusha [124]

Answer:

A. 49 + 16 (t - 1)

Step-by-step explanation:

Plug in t = 1 to test for the first hour:

49+16(1-1)=49+16(0)=49

Test as many values as you like, but testing t = 5:

49+16(5-1)=49+16(4)=49+64=113

You can see that plugging in just a few values confirms the answer.
