Answer: $611</h3>
Work Shown:
30% of 470 = 0.30*470 = 141
The value goes up by $141, so the answer would be 470+141 = $611
A slight shortcut would be to say
1.30*470 = 611
This works because 1.30 = 1 + 0.30 = 100% + 30%
Supplementary, complementary, neither
x - 2y = -4 solve for y to find slope
x - 2y = -4 - subtract x from both sides
-2y = -x - 4 divide y -2 on both sides
-2 -2
y = 1/2x + 2 (-x/-2 is -1/-2x of 1/2x)
Independent variable: number of bagels
dependent: total cost
because: cost depends on the number of bagels
N(x)= 1.5x
N(12)= 18
meaning: 12 bagels costs $18
hope this helps
