Set it up as 15x-13+8x+29+2y=180 and then just find a algebra calculator and put that formula in there
Answer:
Step-by-step explanation:
1 pound = 16 ounce
6 pound = 6 * 16 = 96 ounces
Cost of 96 ounces of grapes = $18
Cost of 1 ounce of grape = 18/96
Cost of 72 ounces of grape = 18*72 / 96 = 27/2
= $13.50
Or
Direct Proportion because is weight increase, the cost will increase
96:18 = 72 : x
Product of means = Product of extremes
18*72 = x*96
18*72/96 = x
x =$13.50
Answer:
89% of Angel's action figure collection keeps on his wall.
Step-by-step explanation:
<u>Percentages</u>
To calculate the X% of a quantity Y, we must multiply both numbers and divide by 100:
X% of Y = X * Y / 100
For example, 15% of 780 = 15 * 780 / 100 = 117
If we want to know what percentage is m with respect to n, we proceed as follows:
percentage = m / n * 100%
Anges has a 300 action figures collection, 267 of which are kept on his wall. Here m=267, n=300, thus:
percentage = 267 / 300 * 100% = 89%
89% of Angel's action figure collection keeps on his wall.
