150 + 130 = 280 combined 
they donated 1/4 of the total amount....1/4(280) = 280/4 = 70....so now they have 280 - 70 = 210
then they spent 40%.....210 - 0.4(210) = 210 - 84 = 126..what they have left

35% of 280 = 0.35(280) = 98


Jay is not correct

What is the solution of log (t minus 3) = log (17 minus 4 t)?<br> 4<br> 5<br> 15<br> 20
Tcecarenko [31]

Option A: 4 is the solution

Explanation:

The given expression is \log (t-3)=\log (17-4 t)

We need to determine the solution of the expression.

<u>Solution:</u>

The solution of the expression can be determined by solving the expression for t.

Let us solve the given expression.

Applying the log rule, if \log _{b}(f(x))=\log _{b}(g(x)) then f(x)=g(x)

Thus, we have;

t-3=17-4 t

Adding both sides of the equation by 4t, we get;

5t-3=17

Adding both sides of the equation by 3, we have;

5t=20

Dividing both sides of the equation by 5, we get;

t=4

Hence, the value of t is 4.

Therefore, the solution of the given expression is 4.

Thus, Option A is the correct answer.

C = 0.20m + 2.00 what is the charge for 1mile ride?
RUDIKE [14]
All you have to do is substitute the 1 into the m for the mile ride:
C = 0.20(1) + 2.00 = 0.20 + 2.00 = 2.20

The charge for 1 mile ride is $2.20.
