Salma is saving money to buy a bike. She has $42 and is going to save an additional $7 each week. The bike costs $133. In how many weeks will she have enough money to buy the bike?

13 weeks

Step-by-step explanation:

if salma is going to save $7 for a week then

minus 42 from 133 to know the remaining amount she needs to feel. which is 91.

1W=$7

?=$91

$91×1÷7=13 Weeks

x/3-10=8

x/3=18

x=48

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
