Ayako spent $7.80 on equal weights of beads of white and red beads. the red beads cost twice as much per punce as the white beads. how much did ayako spend on each colour of beads?

$2.60 on white beads and $5.20 on red beads

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
