Answer:
$12 + $25 = $37
9.25% of 37 is 3.4225 (rounds to 3.42)
$37 + $3.42 = $40.42
Sales tax: $3.42
Total amount spent: $40.42
Answer
It is 112
Step-by-step explanation:
Answer:
3.5
Step-by-step explanation:
To find the constant of proportionality between y/x you investigate the trend in values of x with corresponding values of y
For this case, when x =1, y=3.5
when x=2, y=7
Taking in case 1, y/x = 3.5/1 = 3.5
In case 2, y/x= 7/2 = 3.5
But you know that the constant of proportionality k is given by;
y=kx------------------------making k subject of formula
y/x=k
Hence in this case, your constant of proportionality is 3.5
The answer is A
