Answer:

a). x=18x2

18x2=36

Don spent 36 dollars.

b). x=36x0.3

36x0.3=10.8

Brad's sister spent 10 dollars and 80 cents.

c). 36+18=54

1.0-0.13 = 0.87

54x0.87=46.98

54-46.98=7.02

Don and Brad paid 7 dollars and 2 cents in tax.

How do you write 0.05 times 10=0.5 as division

yaroslaw [1]

0.05 * 10 =0.5

If you want an equivalent expression as division simply divide both sides by either 0.05 or 10 and it'll be dividing:

10 = 0.5/0.05 OR 0.05 = 0.5/10

kotykmax [81]
