(1 point) Mike and Lisa are brother and sister. Mike has as many brothers as sisters, and Lisa has three times as many brothers

Elza [17]

Answer:

Step-by-step explanation:

Given that Mike and Lisa are brother and sister. Mike has as many brothers as sisters, and Lisa has three times as many brothers as sisters

i.e. If Mike has x sisters, then he has x brothers.

i.e. no of sons in total = x+1 (including Mike)

No of daughters = x

Lisa's brothers = x+1 and and Lisa sisters = x-1 (exclusing Lisa)

Given that

$x+1 =3(x-1)\\2x =4\\x=2$

Hence we find that there are 3 sons and two daughters in the family.

Taylor charges $15 for the first hour of dog walking and $10 for each additional hour or fraction of an hour. The rates that Luc

svetoff [14.1K]

Answer:

Taylor will charge more by $15

Step-by-step explanation:

Given

Taylor

First Hour = $15

Hourly Rate = $10

Lucy:

$f(x) = \left \{ {{20x,\ 0 \le \ x \ \le 2} \atop {10x, x>2}} \right.$

For a dog walk of 2.5 hours.

Taylor's charges is:

$Charges = First\ Hour + Hourly\ Rate * 2.5$

$Charges = \$15 + \$10 * 2.5$

$Charges = \$15 + \$25$

$Charges = \$40$

Lucy's charges is:

Here, we consider

$f(x) = 10x$ Because $x > 2$

i.e 2.5 > 2

So, Lucy's charges is:

$Charges = 10 * \$2.5$

$Charges = \$25$

By comparison;

Taylor will charge more by $15

The difference is calculated by:

$Difference = \$40 - \$25$

$Difference = \$15$
