In △RST sinR=0.4 and m

So for the first type of fabric that costs $8 per yard, you first multiply the 8 by the 2 to get $16. Now we need to find 3/4 of 8, because if $8 is 1 yard, then 3/4 of 8 will be 3/4 of a yard. 8 ÷ 4 = 2, 2 × 3 = 6. Now we add the 6 on to 16 to get $22. For the second fabric, we do the same except with a 6. Since the whole number is a 1 there is no need to multiply, so we can go straight on to finding 2/3 of 6. 6 ÷ 3 = 2, 2 × 2 = 4. $6 + $4 is $10. Finally, we add the $10 onto the $22 and we get $32, which is the answer. I hope this helps you!
