Vienna bought 8 yards of fabric and paid $35.60. How many more yards can she purchase with $20?

(The paper this is one is due tmr. Help)

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

The answer is c. 7 (i think) i’m almost sure though
