Step-by-step explanation:
I think not sure but i think the discout is $5.76
50+30y
It is 30y because there are 7 days in a week and each week you deposit $5 so 5*7 is 30.
3x8+4 because 3 times so that is 3 x the sum of 8 and 4 so 8+4 together it would be 3x8+4
The answer is C, 25% increase. To find the increase, subtract starting value (780) from the final value (975). It equals out to be 195. Divide 195 by the starting value which turns out to be 0.25. Then, multiply 0.25 by 100 which equals out to be 25.
