estimate a 15% tip for a $26.80 meal.

a) $4.05

b) $2.70

c) $31.05

d) $1.35

a) $4.05

Step-by-step explanation:

Given,

The cost of the meal = $ 26.80,

Tip percentage = 15%,

Therefore, the amount of tip = 15% of the cost of the meal,

Which is nearer to $ 4.05 from the given option.

Hence, option (a) would be correct.

this is answer of 144 cubic meters

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
