0.30<em>x </em>is the cost of the first type of soda. 0.35(<em>x</em>+4) is the cost of the second type of soda. Put these into an equation looking like:
Cost of Soda A + Cost of Soda B = Total Cost
0.30<em>x </em>+ 0.35(<em>x</em>+4)=3.35 --> Expand 0.35(<em>x</em>+4)
0.30x + 0.35x + 1.4 = 3.35 --> Add the <em>x</em>'s and subtract 1.4
0.65x = 1.95 --> Divide by 0.65
x = 3

Answer:
130
Step-by-step explanation:
Given the equation of the relation as c(h) =50 +20 h where c(h) is the total cost for h hours and h is the number of hours of use, then to find the cost of jet ski if 4 hours were used will be;
c(h)=50 +20 h
c(4)=50 +20*4
c(4)=50 +80
=130
I'm guessing that this one is another complementary angle, so the equation should be 90- 30= (THE ANSWER VARIABLE). Again, complementary angles add up to 90 degrees.
