Sarah purchased 2 pounds of cheese for $8.00. Arun purchased ½ pound of cheese for $2.50. How much more does Arun pay per pound of cheese?

$1 more per pound

Step-by-step explanation:

Sarah: 8/2= $4

Arun: 2.5*2 = 5

Arun pays $1 more per pound of cheese than Sarah

2.50x2=5

Step-by-step explanation:

2.0+2.0=4

.50+.50=1

4+1=5

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

50-38=12
