Answer:

About 60-65$

Step-by-step explanation:

Because every 3 hours she gets $25 and she worked 7 hours so there's 6 in 7 hours so 25+25 is 50 and the other hour would be half of 25 so 12.5 so between 60-65. Im so sorry if its wrong hope it worked tho! <3

Answer:

$58.33

Step-by-step explanation:

Set up a proportion where x is the amount she makes for 7 hours:

\frac{3}{25} = \frac{7}{x}

Cross multiply and solve for x:

3x = 175

x = 58.33

So, after working for 7 hours, she will make $58.33

Jonas has been saving for a video game . last year it costs $28 this year it costs $36 find the percent of change in the cost .
iren2701 [21]

Answer:

Last year the cost was $28.

This year the cost is $36.

$36 - $28 = $8

Percent of increase = amount of increase ÷ original amount

$8/$28 = $0.286

$0.286 · 100 = 28.6%

There has been a 28.6% of change in the cost.

Answer:

y = -0.8x - 5

Step-by-step explanation:

x1 = (XA + XB) / 2 = -5

y1 = (YA + YB) / 2 = -1

m = (XA - XB) / (YA - YB) = -0

__________________________________________

(y - -1) = -0.8(x - -5)

y - -1 = -0.8x - 4

y = -0.8x - 4 + -1

y = -0.8x - 5
