This is going to be long but here i go

sally is paid a fixed amount of money to walk her neighbors dog every day after school. when she is paid each month, she puts aside $20 to spend and saves the remaining amount. write an expression that represents the amount sally will save in 6 months if she earns m dollars each month. if sally paid $65 each month, how much will she save in 6 months?

Expression : 6m - 120

Savings: $270

Step-by-step explanation:

Expression: 20 * 6 = 120

so you save $120 dollars every 6 months

Savings: 6(65)-120

^^substitute "m" for her pay or 65 in this case

390-120

^multiply 6 * 65

270

^subtract 390 - 120

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
