c) A coin bank can hold 100 coins. There are 50 coins in the bank. A student puts in 710 coins per week. How many weeks until the bank is full?

d )A coin bank can hold 710 coins. There are 100 coins in the bank. A student puts in 50 coins per week. How many weeks until the bank is full?

Answer 1

The answer is D

Explanation:

The original equation ..

100x +50 = 710

100x=710-50

100x=660

Divide on both sides

X =6.6

When you solve equation D in the same way, the same result will appear

Answer 2

A

Explanation:

Because for A, the question is "How many weeks until the bank is full?" which is looking for X. That part is checked off. It says 100x+50=710. 710 is the total in A too so that is checked off. In the equation, the piggy bank starts with 50 coins so that is checked off. Everything is in order so A is the answer. WEAR A MASK AND STAY SAFE DURING THIS HARD TIME! ;)
