Amir has $100 and is saving $5 per week to buy a new DVD player. Pete has $80 and is saving $7 per week to buy the same DVD player. Which system of equations can be used to find w, the number of weeks it would take for them to have m, the money needed to buy the DVD player

m= 100+5w

m= 80+7w

Step-by-step explanation:

Let w = number of weeks , m = Money required to buy DVD.

Total money = (Initial saving) + (Money saved per week) x (Number of weeks)

For Amir,

initial saving = $100 , Money saved per week =  $5

So,  m= 100+5w

For Pete,

initial saving = $80 , Money saved per week =  $7

So,  m= 80+7w

So, the required system of equations to find m and w:

m= 100+5w

m= 80+7w

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
