She has 19 total.
Start out with 9 blue.
7 fewer yellow would be 2 yellow.
4 times as many green as yellow is 2 times 4 which is 8.
9+2= 11
11+8= 19
She would save $9.12 by using the better sale! I hope this helped!:)
5.702 rounded to the nearest unit is 6. Look one decimal place further to determine what to round to. Greater than or equal to 5, round up. Less than 5, keep it the same.
For example, 5.402 rounded to the nearest unit would be 5 because the next decimal point is 4
