Answer:
$53.46
Step-by-step explanation:
If the meal was $43.45 and there is a sales tax of 7% then we can think of it as 100% of the meal plus 7% therefore 100%+7%=107%. Since 107% is equal to 1.07 in decimals the meal plus the sales tax is:
[tex]43.45 \times 1.07 = 46.49[/tex]
Now the Jackson family is going to tip 15% on the meal and sales tax, meaning $46.49 + 15%. Similar to above 100% + 15% = 115% = 1.15. And so:
[tex]46.49 \times 1.15 = 53.46[/tex]
