Quita bought a jacket priced at $90. The sales tax rate on the jac was 7%.
How much was the sales tax in dollars and cents on this jacket

Sales tax= $6.30

Jacket= $0.9630

Step-by-step explanation:

Jacket price= $90

Sales tax= 7%

Sales tax in dollars

=7/100×90

=$6.30

Jacket in cents

=$90+$6.30

=$96.30 ÷100

=$0.9630

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
