Jane invested her savings in two investment funds. The amount she invested in Fund A was $4000 less than the amount she invested in Fund B. Fund A
returned a 5% profit and Fund B returned a 3% profit. How much did she invest in Fund B, if the total profit from the two funds together was $1320?

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

probably .5

i can on others if necessary.

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
