Write an expression to represent the amount of money saved after x weeks. Then use your expression to complete the following table. Number of Weeks Amount of Savings ($) 1 96 2 ? 3 ? 4 ? Write and solve an equation to find the number of weeks it will take Tayla to save the $360.
Write this whole thing in the form of a sheet of paper.
Melissa gets $2 more a week in allowance than 2 times Monica’s allowance. If Melissa gets $20 in allowance each week, Monica’s allowance can be represented by the equation:
Melissa’s Allowance = 2(Monica’s Allowance) + $2
$20 = 2(Monica’s Allowance) + $2
Subtract $2 from both sides:
$18 = 2(Monica’s Allowance)
Divide both sides by 2:
$9 = Monica’s Allowance
Christina charges a flat fee of $10 plus $3 per child when she babysits for an hour. If Christina made $16 an hour, the number of children she babysat can be represented by the equation:
$16 = $10 + $3(Number of Children)
Subtract $10 from both sides:
$6 = $3(Number of Children)
Divide both sides by $3:
2 = Number of Children
There are 27 basketball teams in the Storyville Park District. This is 5 less than 2 times the number of teams in the Friendly Village Park District. Let the number of teams in the Friendly Village Park District be represented by the variable x. The equation can be set up as:
27 = 2x - 5
Add 5 to both sides:
32 = 2x
Divide both sides by 2:
16 = x
So, there are 16 basketball teams in the Friendly Village Park District.
Let the cost of 1 t-shirt be represented by the variable t. The cost of the poster and the t-shirts can be represented by the equation:
4t + $14 = $98
Subtract $14 from both sides:
4t = $84
Divide both sides by 4:
t = $21
So, 1 t-shirt costs $21.
Talya is saving $24 per week to buy a $360 video game system. The expression to represent the amount of money saved after x weeks is:
Amount of Money Saved = $72 + $24x
Using this expression, we can complete the following table:
Number of Weeks Amount of Savings ($)
1 $72 + $24(1) = $96
2 $72 + $24(2) = $120
3 $72 + $24(3) = $144
4 $72 + $24(4) = $168
To find the number of weeks it will take Talya to save $360, we can set up and solve the following equation:
$72 + $24x = $360
Subtract $72 from both sides:
$24x = $288
Divide both sides by $24:
x = 12
So, it will take Talya 12 weeks to save $360.
