8 0

Answer:

81%

Step-by-step explanation:

Average score= total score ÷number of tests

To find the average score for all ten tests,

① Find the total score for all ten tests

② Divide the total score by the number of tests, 10

Let's find the total score for the 1st 4 tests first.

Total score

= 4(75%)

= 300%

For the next 6 tests,

total score

= 6(85%)

= 510%

Total score for 10 tests

= 300% + 510%

= 810%

Average score

= 810% ÷10

= 81%

vaieri [72.5K]

Answer:

Harry has a loan of $9000 in total. Harry obtained a loan from the bank. Explanation Harry's remaining debt, expressed in dollars, is modeled as a function of time t, expressed in months, by the function D(t). The role is played by, This function can be used to determine that $200 is being subtracted each month from the function, meaning Harry is paying $200 toward his loan. Harry has not yet made any payments, therefore we may set t=0 to obtain the total amount of his solo. Therefore, the value of D(t) will reveal the loan's net amount. Harry's borrowing, therefore, equals to $9000.
