When louisa rented a moving truck, she agreed to pay $28 per day plus $0.42 per mile. if she kept the truck 3 days and the rental charges (without tax) were $153.72, how many miles did louisa drive the truck?
a.
339 miles
b.
340 miles
c.
166 miles
d.
16.6 miles

Option c.

Step-by-step explanation:

Louisa kept the truck for 3 days, so her daily fix charge = $28 × 3

                                                                                            = $84

She paid her rental without tax = $153.72

Her travelling charges are = 153.72 - 84 = $69.72

Her charges per mile = $0.42

She traveled = 69.72 ÷ 0.42 = 166 miles

Louisa drove the truck 166 miles.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
