10 pounds of candy costing $1.20 per pounds must be mixed with 40 pounds of candy costing $ 0.95 per pound to obtain a 50 pounds of candy costing $ 1 per pound
<em><u>Solution:</u></em>
Let "x" be the pounds of candy at $ 1.20 per pound
Then (50 - x) is the pounds of candy at $ 0.95 per pound ( since 95 cents is equal to 0.95 pound)
Therefore, x pounds of candy costing $1.20 per pounds must be mixed with (50 - x) pounds of candy costing $ 0.95 per pound to obtain a 50 pounds of candy costing $ 1 per pound
Then the equation becomes,
1.20x + (50 - x)0.95 = 50 x 1
On expanding we get,
1.20x + 47.5 - 0.95x = 50
0.25x = 50 - 47.5
0.25x = 2.5
x = 10
Then (50 - x) = 50 - 10 = 40
So we need 10 pounds of candy worth $ 1.20 per pound and 40 pounds of candy worth $ 0.95 to obtain 50 pounds of candy worth a dollar a pound
Answer:
a
also this is only 5 points not 30
Step-by-step explanation:
it is a because this equation is y=mx+b and b is the y-int and b=2 so 2 is the y int which means x will be 0 and points are written as (x,y) so then it would be (0,2) sorry really bad at explaining
