T(1) = 1^2 = 1T(2) = 2^2 = 4T(3) = 3^2 = 9T(4) = 4^2 = 16T(5) = 5^2 =25

Jada's sister works in a furniture store.

Bingel [31]

Answer:

1) $16.35

2) 75%

3) $245

Step-by-step explanation:

1) Jada earns = $15 per hour

9% increase = 15 * 9/100 = $1.35

Increased Jada's pay = 15+1.35 = $16.35

2) Markup = selling price - cost= $350 - 200= $150

Markup % = $\frac{sale price - cost }{cost}*100$ \

= $\frac{150}{200}*100$ = 75%

3) Jada's sister commission is 3.5% of $7000

= $\frac{3.5}{100}* 7000$

= $245

tim spent 24 at the grocery store this was six dollars less than two timeswhat he spent at the game store how much did he spend

Svetlanka [38]

Money spent at grocery store = x, money spent at game store = y
x = 24
x = 2y - 6

24 = 2y - 6
24 + 6 = 2y
30 = 2y
30/2 = y
15 = y <=== spent 15 at game store
