Answer:
x = 22/25
Step-by-step explanation:
Given
2 1/5 x
---------- = -----------
10 4
Using cross products
2 1/5 * 4 = x*10
Change 2 1/5 to an improper fraction
2 1/5 =(5*2+1)/5 = 11/5
11/5 *4 = 10x
44/5 =10x
Multiply each side by 1/10 to isolate x
44/5 *1/10 = 10x * 1/10
44/50 = x
Divide top and bottom by 2
22/25 = x
4.75/100= 0.0475 <--- unit rate
0.0475*225= 10.6875
Round to 10.69. <-- cost for 225 pencils

Answer:
y=-3/4x+3
Step-by-step explanation:
the slope is -3/4
in this case, y=mx+b
so y=-3/4x+b
b is the y intercept, so it would be 3
altogether, y=-3/4x+3
