During the first hour of the bake sale christhopher sold $25 worth of goods

is that all

Step-by-step explanation:

(1) The average price for the items sold during that hour was $1.42 --> 1.30c+1.50bc+b=1.421.30c+1.50bc+b=1.42 --> 8b=12c8b=12c --> cb=23cb=23. Sufficient.

(2) The total price for all the goods sold was $14.20. This statement is a bit trickier: 1.30c+1.50b=14.201.30c+1.50b=14.20 --> 13c+15b=14213c+15b=142. Since c and b must be integers, then we should check whether this equation has one or more than one positive integer solutions: 15b=142−13c15b=142−13c --> 142 minus multiple of 13 must be a multiple of 15: only c=4 and b=6 satisfies the equation, thus cb=46cb=46. Sufficient.

Step-by-step explanation:

(1)

1.30c+1.50bc+b=1.421.30c+1.50bc+b=1.42

1.30c+1.50b=1.42(c+b)1.30c+1.50b=1.42(c+b)

1.30c+1.50b=1.42c+1.42b1.30c+1.50b=1.42c+1.42b

0.08b=0.12c0.08b=0.12c

cb=0.080.12cb=0.080.12

cb=23cb=23

Sufficient

(2)

1.30c+1.50b=14.201.30c+1.50b=14.20

the only possible solution is:

1.30(4)+1.50(6)=14.201.30(4)+1.50(6)=14.20

Ratio is 4:6 or 2:3

Sufficient

Answer is D

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
