Answer:

C, D and E

Step-by-step explanation:

Given

Represent solid beads with S and clear beads with C

So:

S:C = 8:20

Required

Select operations that give an equivalent ratio

First, we need to get the unit ratio

S:C = 8:20

Divide through by 4

S:C = 2:5 -- This means that, after any operation. The equivalent ratio must be 2: 5

Option A: Add 2 to S and 2 to C

S:C = 8:20

Perform the operation

S:C = 8 + 2 : 20 + 2

S:C = 10 : 22

Divide through by 2

S:C = 5:11

Option B: Subtract 8 from S and 6 from C

S:C = 8:20

Perform the operation

S:C = 8 - 8 : 20 - 6

S:C = 0 : 14

Option C: Multiply S and C by 2

S:C = 8:20

Perform the operation

S:C = 8*2:20*2

S:C = 16:40

Divide through by 8

S:C = 2:5

Option D: Divide S and C by 4

S:C = 8:20

Perform the operation

S:C = 8/2:20/4

S:C = 2:5

Option E: Multiply S and C by 18

S:C = 8:20

Perform the operation

S:C = 8*18:20*18

S:C = 144:360

Divide through by 72

S:C = 144/72:360/72

S:C = 2:5

<em>From the calculations above, options C, D and E gave an equivalent of 2:5.</em>

choli [55]
Let C be Clowns R Fun charge for b balloons and S be Singing Balloons charge.
C=6+1.25b and S=2+1.95b. C must be less than S.
6+1.25b<2+1.95b, 4<0.7b, b>4/0.7, b>40/7, b>5. So Mrs Travis needs to purchase more than 5 balloons.
