Julia gets paid a weekly allowance of x. She earns an additional amount, y, each time she walks the family dog.
Write the expression that would represent the total amount Julia receives for 3 weeks if she walked the dog 7 times.
She receives "x" amount for three times in three weeks
And she receives y each time she walks the dog..and she does this seven times...so calling T the total amount she receives, we have
T = 3x + 7y
Thanks a lot!
