When gisselle decided to stop eating junk food, she started saving more of her allowance to buy a larger bicycle. she managed to put away 6 every week for 8 weeks and found a nice used bicycle for 50. she thought that she had close to that amount in her savings jar. did she have exactly enough for the bicycle? if now, how much extra or how much too little did she have?

Gisselle had $48 saved, which is $2 less than what she needs.

Step-by-step explanation:

Since Gisselle is saving $6 every week and she is able to save for 8 weeks, we can either add all of her savings together, or we can multiply:

Week 1 = $6

Week 2 = $6

Week 3 = $6

Week 4 = $6

Week 5 = $6

Week 6 = $6

Week 7 = $6

Week 8 = $6

Total = $48

Also:  $6 x 8 = $48

Since the used bicycle is $50, we can subtract:

$50 - $48 = $2 that Gisselle still needs to buy the bike.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
