Question

Terri is trying to save $250 so she can buy a new surfboard . She has \$75 saved already and plans to save $45 per week . How many weeks will it take her to save up enough money to purchase a new surfboard ?

Answer 1

Answer:

It will take Terri 4 weeks to save up enough money for a new surfboard.

Step-by-step explanation:

250-75= 175

175/45= 3.888

But its asking for whole weeks, so round to the nearest whole number, which is 4.

btw 45x4= 180 so she'll have 5 extra dollars.

Answer 2

$250=$75+$45 •x
x= number of weeks
250=75+45•x
75+45•x=250
45•x=250-75
45•x=175
x=175/45
x=3.88
Terri needs to save money for at least 4 weeks.
4•45=$180
$180+$75=$255
