Answer:

411

Step-by-step explanation:

[tex]15 \div 100 \times 420 = 63[/tex]

[tex]420 - 63 = 357[/tex]

15

[tex]15 \div 100 \times 357 = 53.55[/tex]

this is the 15% up amount

[tex]357 + 53.55 = 410.55[/tex]

nearest whole number is 411

I think the answer is 412 or 411 I’m not really fully fully sure which one
