Question

A music student needs $500 to buy a keyboard. She has $120 and is saving a certain amount each month. He only has 6 months to save the money. Write an inequality to determine the least amount of money, m, he needs to save each month to meet the deadline?

Answer 1

m=64x+120

x being the number of months

y=64x+b when using variables x and y

Explanation:

She needs $500 and has $120

meaning she needs to save $380 in a total of six months.

Each month she will save the same amount of money.

So then we get $380/6 = $63.3333333

From here you can round up to $64 a month or $63.34 if cents are included.

Ask me for more info if you need to answer the problem differently

Possible answers:

y=64x+120

m=$64 a month + $120

y=63.33333+120

y=$63.34 + 120
