Answer:
$2.59
Step-by-step explanation:
Let b and m represent the costs of a banana split and a milkshake, respectively. Then the two purchases are ...
b +5m = 16.24
3b +2m = 15.05
Subtracting the second equation from 3 times the first, we have ...
3(b +5m) -(3b +2m) = 3(16.24) -(15.05)
13m = 33.67 . . . . . . simplify
m = 2.59 . . . . . . . . . divide by 13
The cost of a milkshake is $2.59.
Answer:
39 degrees
Step-by-step explanation:
The sum of angle in the triangle ABC is a80 degrees
m<ACB + <BAC + <ABC =1 80
90 + <BAC + 51 = 180
141 + m<BAC = 180
m<BAC = 180-141
m<BAC = 39 degrees
Hence the measure of m<BAC is 39 degrees
0.15p , p < $900
C(p) = 0.17p, $900 < p < $1,500
0.21p, p > $1,500
