Jinney wants to deduct the sales tax that she paid this year on her state income return. she paid $4960.80 during the year, including 6% sales tax. how much sales tax did she pay?

T = state income return (without sales tax)

106% of t = 4960.80
AKA
1.06t = 4960.80 --> Divide both sides by 1.06 to find the state income return without sales tax
t = 4680 

Subtract t from the state income return with sales tax.

4960.80 - 4680 = 160.80

She paid $160.80 in sales tax.

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
