Answer:
-18
Step-by-step explanation:

A. 14.43
13.36x0.08 = 1.068
13.36+1.068 = 14.428 (round up) 14.43
The sales tax can be found through multiplying the total by the decimal form of the given sales tax (7.5=0.075). This operation yields 40.5 or $40.50. I really hope this helps!:)
Answer:
i think you would multiply them but I'm not sure
Answer:
y = 0.5x + 4, or y = 1/2x + 4 (if you prefer fractions)
Step-by-step explanation:
y = mx + b (slope intercept form / standard form) ; m = 0.5 or 1/2, b = 4.
m = linear coefficient/slope(denoted by <u>a</u> in a 1 degree binomial)
b = constant coefficient / y-intercept (denoted by <u>b</u> in a 1 degree binomial)
to convert this equation into a standard form equation. You need to isolate y and leave the coefficients on the other side.
0.5x = y - 4
0.5x (+4) = y - 4 (+4)
0.5x + 4 = y
y = 0.5x + 4
