Equivalent ration of b/40=9/10 b=____ ?

Mathematics
1 answer:
NARA [144]3 years ago
7 0

Answer:

The correct answer is <em>b = 36</em>

Step-by-step explanation:

In order to find out what b is, you must find out what 9/10 is.

9/10 is 0.9. This will later be used to check our answer.

Now, solve by using cross-multiplication

b * 10 = 9 * 40.

Then use the commutative property to reorder the terms

10b = 9 * 40

Now Multiply 9 * 40 = 360

10b = 360

Now divide both sides of the equation by 10

<em>b = 36</em>

attashe74 [19]

Answer:

$56

Step-by-step explanation:

The jacket is on sales for 30% off the original price = (0.3)

The original price (P) = $80

However, the expression "p - 0.3p" is to be used to find the sales price

The sale price = p - 0.3p

The sale price = $80 - 0.3($80)

The sale price = $80 - $24

The sale price = $56
