Answer: See each one below:
1) Since she is paying for 30% of the cost, we multiply it by 0.3. Then, since it is over the whole year, we divide it by 12.
12304 * 0.3 / 12 = 307.6 B
2) First, we subtract the cost of the 50 deductible, then multiply the amound by 0.2 because he has to pay 20% of the balance.
1060 - 50 = 1010 x 0.2 = 202 A
3) First, we find the total cost of the visits. Mattie has to pay for 40% so times it by 0.4. Then, don't forget to add in the cost of 12 co-pays of $15 each.
3660 * 0.4 = 1464 + 15(12) = 1664 B
<u>IF YOU NEED SLOPE-INTERCEPT FORM</u>
2x + 3y - 7 = 0
3y = -2x + 7
y = -
+ 
<u>IF IT IS KIND OF HOW YOU WROTE IT:</u>
If it is 2x+3y-7=2x+3y-7 then the solution is 1
IF THIS IS NOT WHAT YOU NEED, <em>PLEASE </em>COMMENT WITH MORE CONTEXT! :D
Y = 172.972972972...
You need to isolate the variable, y. To do this, you need to divide both sides of the equation by 0.74. This gives you your final answer.
You know that 3 times 2 is 6 so 30'times 20 equals 60
