A rental company charges costumers a 14.75 fee plus $0.15 per smile to rent a moving van after returning the moving van a custom
kumpel [21]

Step-by-step explanation:

I guess, the question is, how many miles were driven ?

if that is the case, then

we need to deduct the basic fee of $14.75, as this would have been paid, even if they did not drive a single mile.

so, 50.45 - 14.75 = $35.70

that is the actual cost for the driven miles.

how many miles ?

well, how often do $0.15 fit into $35.70 ?

35.7 / 0.15 = 238 miles.

this customer had been driving the moving van for 238 miles.

ESTIMATE THE ANSWER BY ROUNDING EACH NUMBER TO THE NEAREST 10. 961 + 27.8 + 693.0 + 573 +76.4 =
taurus [48]

Answer:

2330

Step-by-step explanation:

In rounding nearest 10,

If the ones place digit is 5 or more then 5 then we round the number to upper 10, while if the ones place digit is less than 5 then we round the number to lower 10,

For example : 34 ≈ 30 while 36 ≈ 40,

Now, given expression,

961 + 27.8 + 693.0 + 573 +76.4

By the above statement 961≈ 960, 27.8 ≈ 30, 693.0 ≈ 690, 573 ≈ 570 and 76.4 ≈ 80,

Hence, 961 + 27.8 + 693.0 + 573 +76.4 = 960 + 30 + 690 + 570 + 80 = 2330.
