Jenny and lenny pick 1/4 and 1/3 of a tree full of apples, respectively. penny picks the rest of the apples. if lenny picks 7 more apples than jenny does, how many apples does penny pick

Penny picks 35 apples

Step-by-step explanation:

first, you need to multiply the fractions to get equal denominators.

(1/4)*3=3/12 and (1/3)*4=4/12

then add the results,

3/12+4/12=7/12

to work out what fraction was picked by Penny, use 12/12(total amount as a fraction with equal denominator)

12/12-7/12=5/12

then to work out how many apples were picked by Penny(P), Jenny(J), and Lenny(L)

J=3/12, L=4/12, P=5/12.

if Lenny picks 7 more than Jenny, then each twelfth of the apples is 7 apples. therefore,

12*7=84 total apples

Penny picks 5 twelfths, therefore,

5*7=35 apples

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
