Betty took her two daughters out to lunch. Betty's meal was $15.50 and her daughter's meals were $13.45 and $16.75. If Betty is going
to leave a 20% tip, what is the total amount of the meal?

$9.14

Step-by-step explanation:

$15.50 + $13.45 + $16.75 = $45.70

   x              20%

45.70           100%      Cross multiply

45.70  x 20 = 914

914 divided by 100 = 9.14

take it another

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
