Multiply 4.50 x 10= 45.00$

Step-by-step explanation:

$7.50

Step-by-step explanation:

Divide the cost by 6 to find the price of one 1lb:

4.50 ÷ 6 = 0.75

Now multiply this by 10 to find the cost of 10lbs:

0.75 x 10 = 7.5

∴ The cost is $7.50.

Hope this helps!

yes

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
