Answer: the store charged $40 for the bike helmet before tax.
Step-by-step explanation:
Let x represent the amount that the store charge for the bike helmet before tax.
If the sales tax rate was 8%, it means that the amount of tax that was charge is
8/100 × x = 0.08 × x = 0.08x
Monica paid sales tax of $3.20 when she bought a new bike helmet. This means that
0.08x = 3.2
Dividing the left hand side and the right hand side of the equation by 0.08, it becomes
0.08x/0.08 = 3.2/0.08
x = 40
Your answer should be B!

-7 and -8
Step-by-step explanation:
a negative times a negative is a positive and -7 times -8 is 56 and -7 plus -8 is -15:)
8668/25 + 4141/9 - 5533/25.....common denominator is 225
78012/225 + 103525/225 - 49797/225 =
181537/225 - 49797/225 =
131740/225 =
585 115/225 =
585 23/45
so the fraction part of the mixed number is 23/45
