Step-by-step explanation:
Step 1: Write down the percent divied by 100 like this: percent/100
Step 2: If the percent is not a whole number, then multiple both top and bottom by 10 for every number after the decimal point. (for example, if there is on number after the decimal, then use 10, if there are two then use 100, ect.)
Step 3: simplify.(or reduce) the fraction
Answer:
19.26
Step-by-step explanation:
price sold for= 12×150%
= 18
total cost = 18 × 107%
= 19.26
Answer:
y - 1 = - 4(x + 3)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 4 and (a, b) = (- 3, 1), hence
y - 1 = - 4(x - (- 3)), thus
y - 1 = - 4(x + 3) ← in point- slope form
The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Find the values of m and b using the form y=mx+b y = m x + b . The slope of the line is the value of m , and the y-intercept is the value of b .
