Answer:

B - 2 hours

Step-by-step explanation:

find the rate for each scenario until you find one that matches.

for A 1 hour:

Ben charges (15.50×1hour) = 15.50

Cathie charges (9.25 × 1 hour) + 12.50 flat fee = 21.75

THESE DO NOT MATCH

so you do B 2 hours:

Ben charges 15.50× 2hours = 31

Cathie charges (9.25 × 2hours) + 12.50 flat fee = 31

THESE MATCH SO THIS IS THE ANSWER

If you continue like this for 3 hours and 4 hours the values don't match. so the only answer is B.

Brad has eight more nickels than quarters. Altogether he has $6.10. how many of each does he have

wlad13 [49]

Brad have 19 quarters and 27 nickels.

Step-by-step explanation:

Given,

Total worth of nickels and quarters = $6.10 = 6.10*100 = 610 cents

One quarter = 25 cents

One nickel = 5 cents

Let,

x represent the number of quarters.

y represent the number of nickels.

According to given statement;

25x+5y=610 Eqn 1

y = x+8 Eqn 2

Putting value of y from Eqn 1 in Eqn 2

$25x+5(x+8)=610\\25x+5x+40=610\\30x=610-40\\30x=570$

Dividing both sides by 30

$\frac{30x}{30}=\frac{570}{30}\\x=19$

Putting x=19 in Eqn 2

$y=19+8\\y=27$

Brad have 19 quarters and 27 nickels.
