Answer:2881
Step-by-step explanation:
Answer:
The factors are (x-4) and (x+1)
(x-4)(x+1) = x²+x-4x-4 = x²-3x-4
Step-by-step explanation:
(x-4)(x+1) = x²+x-4x-4 = x²-3x-4
This is how you solve it; but first of all convert the percent into a decimal;55%= 0.55
0.55x = 164 (divide by 0.55 on both sides)
x = 164/0.55
x = 298.18 (rounded to the nearest hundredth)
so 164 is 55% of 298.18(rounded)
70 times .9 is 63 so 90 minus 63 is27 so it was $27
