Answer:
347 = 257 + 45x
Step-by-step explanation:
To create an equation representing this scenario, we have to have an equation equaling 347, which is the total amount in $ that Bruce owes his friend.
347 =
We know that Bruce made a downpayment of 257, so that must go on the right side of the equation since that is part of what bruce paid back of the total $347.
347 = 257 + ?
Now we need to create a term representing the rest of the money Bruce will pay back. X represents the number of months Bruce will pay his friend $45. If the number of months is multiplied by 45, we will get the amount of money Bruce paid after his initial downpayment of $257. Put this into our equation to make the equation true.
347 = 257 + 45x
Now, let's solve for x.
Subtract 257 on both sides.
90 = 44x
Divide by 45 on both sides.
2 = x
Bruce must pay $45 dollars to his friends once a month for 2 months, which means he must pay $90 after the downpayment of $257. We can check our answer by substituting 2 into our equation.
347 = 257 + 45(2)
Multiply 45*2.
347 = 257 + 90
Add 257 and 90.
347 = 347
Our equation is true, so we know that the equation 347 = 257 + 45x accurately represents this scenario and that x = 2.
