Answer:
22
Step-by-step explanation:
i did this yesterday
Total price of 3 yards of fabric - 7.47
7.47 / 3 = 2.49
2.49 is how much each yard costs
2.49 * 2 = 4.98
4.98 is how much 2 yards of fabric costs
Kenji would pay $4.98 for two yards of fabric without tax.
Answer:
Lucy had 40 books last year.
Step-by-step explanation:
assuming 100% is the percent;
100% + 70%
100 : x
170 : 68
cross multiply = 170x = 100 x 68
-------- ————-
170 170
cancel 170/170
therefore x = 100 x 68 divided by 170
result is 40
# 4 is a function because all the x numbers are only used once
