Nina used 200 beads to make 2 bracelets. 50 of the beads were red. she wrote down that 0.05 of the beads were red. did nina write the decimal correctly? explain.

No she didn't write the decimal correctly. This is because 50 as a decimal is 0.50 and not 0.05

.

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
