Final answer:
Emma can spend $148.80 on items at the music store.
Step-by-step explanation:
To find out how much Emma can spend on items, we need to first calculate the amount of sales tax. The sales tax rate is 7%, so we can find the amount of sales tax by multiplying the total amount of money Emma has by the sales tax rate:
Sales tax = $160 x 0.07 = $11.20
Once we have the amount of sales tax, we can subtract it from the total amount of money Emma has to find out how much she can spend on items:
Amount Emma can spend = $160 - $11.20 = $148.80
Therefore, Emma can spend $148.80 on items at the music store.
