As an estimation we are told ? 3 is €4. convert €83.60 to pounds. give your answer rounded to 2 dp.

€83.60 = £62.70

Step-by-step explanation:

£3/€4 = £x/€ 83.60

¾ = x/83.60

Multiply each side by the lowest common denominator (4 × 83.60)

3 × 83.60 = 4x

Divide each side by 4

x = (3 × 83.60)/4 = £62.70

∴ €83.60 = £62.70

(The conversion factor is out of date. The current conversion factor is closer to £6 = €7.)

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!
