Carolyn is using the table to find 360% of 15. What values do X and Y represent in her table?
Ganezh [65]

★  100% of 15 = X

\implies \mathsf{100\%\;of\;15 = \left(\dfrac{100}{100} \times 15\right) = 15}

\implies \mathsf{X = 15}

★  20% of 15 = Y

\implies \mathsf{20\%\;of\;15 = \left(\dfrac{20}{100} \times 15\right)}

\implies \mathsf{20\%\;of\;15 = 3}

\implies \mathsf{Y = 3}

<u>Answers</u> : X = 15 and Y = 3

soldi70 [24.7K]

Answer:

25m + 10b = 400

Step-by-step explanation:

Total amount that can be earned = $ 400

Amount earned on mowing a lawn = $ 25

Amount earned per hour on babysitting = $10

Amount earned for mowing one lawn is $ 25, so amount earned for mowing m lawns will be $ 25m

Amount earned for one hour of babysitting is $ 10, so amount earned for babysitting for b hours will be $ 10b

Total amount earned = Amount earned from mowing m lawns + Amount earned from babysitting for b hours

Using the values from above, we can set up the equation as:

400 = 25m + 10b
