Spotlight Dance increased the number of dancers on its competition team. Last
Nana76 [90]

Answer:

80%

Step-by-step explanation:

To find percentage increase, we use the following formula:

Percentage Increase = \frac{New-Old}{Old}*100

Here

New means the latest value (which is 18 dancers)

Old means the previous value (which is 10 dancers)

The Multiplication by 100 is to convert the decimal answer to percentage.

So, we have:

New = 18

Old = 10

Now we substitute and find:

\frac{New-Old}{Old}*100\\\frac{18-10}{10}*100\\\frac{8}{10}*100\\80

So, there was an increase of 80%

What is the solution to this system of equations<br>(5z +y=2<br>( 47 +y=5​
prisoha [69]

Answer:

Z = 8.8 Y = - 42

Step-by-step explanation:

Y = 2 - 5Z

Y = 5 - 47

2 - 5Z = 5 - 47

- 5Z = - 44

5Z = 44

Z = 8.8

Y = 2 - 5 (8.8)

Y = 2 - 44

Y = - 41

Y = 5 - 47

Y = - 42

Veronica earns $150 per week plus 3.5% on sales,while Francis earns 6% commission only
marissa [1.9K]

Answer:

a) Veronica earns $276. Francis earns $216

b) $6000

Step-by-step explanation:

Veronica's income would be I= 0.035s +150 where I is income and s is sales while Francis's income would be 0.06s. So for $3600 in sales Veronica earns $276 while Francis earns $216. To find the answer to part b just set the two equations equal to each other and solve for x. so 0.035x + 150 = 0.06x Subtracting 0.035 x from both sides gives 150 = 0.025x. Dividing both sides by 0.025 gives x = $6000
